Ford F-150 (2004-2008) :: 2006 - Jerks / Bogs When Transmission Shifts

I have a 2006 F150 4x4. When the engine an transmission is cold it jerks/ Bogs when it shifts. After it warms up it doesn't jerk to bad sometimes but you can still notice it. Also when it shifts the RPM's drop low causing it to bog and jerk. RPM's will go from 1600 to about 800 when it shifts. It is and auto transmission. Today I wanted to try something so I pressed the button to turn the over drive off. Well it shift real good with the OD Off. Seem like with the OD Off it keeps the RPM's up a little higher so it doesn't bog and jerk. I put an Edge Programmer on it, but that didn't work. Still does the same thing with or without the programmer. I changed all my spark plug and coil packs. Truck goes great until it shifts.

Ford F-150 (2004-2008) :: Transmission Bang When It Shifts And RPMs Drop To Lock Up Range

Truck is 04 supercrew with 5.4 and 140,000 miles. I have the typical shutter when cruising 55 - 60 and just ease on the throttle to pass someone. I chalked that up to the torque converter unlocking, if I punch it instead of easing into it, it will not shutter. As of yesterday, it acts like the converter is going to full lock up almost immediately. It will bang when it shifts and rpm's drop to lock up range. A few times it has killed the engine when I shift into D. No codes at all, I removed the programmer and installed the stock tune, no change, unhooked battery, no change, fluid is good, and twice after leaving stop signs it worked perfect until the next stop. I believe that it is an electrical control problem.

Ford F-150 (2004-2008) :: 2005 - Rough Shifts Occasionally?

I recently purchased a 2005 f-150 4x4 with 115,000 miles. The truck is in overall great shape but does have a mysterious transmission issue i have been chasing for over a month. The truck runs and drives great aside from a occasional rough shift. The overdrive light flashes and the monitor displays "trans fault". I have had the truck to a few different mechanics including the local Ford dealership. It pulls p0702. The truck will manually shift into 4x4 but it will not engage by using the switch. I have replaced: Trans wiring harness, checked all fuses, dropped pan and replaced all wires, nuetral safety switch and a few other misc. parts.

Ford F-150 (2004-2008) :: 2007 - Up / Down Shifts Randomly After New Torque Converter

I bought an 07 F150 5.4 4x4 with 135k on it about 6 months ago. Shortly after buying the truck I began experiencing a shudder when lightly accelerating up a hill. Also when accelerating hard it would misfire. Thinking that it was plugs or COPs I changed the plugs and coils. That fixed the missfire issue but it still shuddered when accelerating up a hill.

I decided to take it back to the used car dealer where I bought it so they could fix it. On the way there the fly wheel broke. The dealer replaced it and thought that it was the cause of the problem but on the way home I still experienced the shudder. I took it back and they "scoped" it and found that the torque converter was bad. They replaced the TC and now there is no more shudder BUT now I have a new problem.

Now if I am driving at highway speed and let off the gas it feels like it immediately down shifts for a few seconds then shifts back up and coasts along until I give it gas again. There is enough resistance that it feels like a jake brake or that the breaks are being applied. Also if driving along at 30 - 40 mph and just holding the gas in the same spot maintaining 30-40 it feels like it down shifts and up shifts over and over until I either give it more gas or let off all together. Also a few times pulling away from a stop I will get a thump.

I have an appointment with a transmission shop in a few days but today on the way home I put it in second gear while going up a hill so it would not shift and it seemed like it was coughing and sputtering. So now I am wondering if that is what is happening and either feeling like or causing the down shift up shift issue.

If it is a missfire issue why would the new torque converter cause this? It has all new motor craft plugs and all new after market coils.

There are no check engine or other warning lights lit on the dash. I have a cheap ODB scanner and it shows two codes. B1676 which apparently is a Battery Pack Voltage Out Of Range or ABS voltage issue. The voltage is showing at 14.2 volts and there is no noticeable battery issues. The second code is a P1000 Drive cycle test not complete. (this code has been showing for some time the 1676 code is new since the torque converter swap)

One side note: after the TC change every time I start the truck the radio/cd changer cycles though all the CDs. like it it is checking for a disk so it clicks and pops around from a moment. The only time I heard this happen before was after having the battery disconnected. The clock is not reset though like I would expect if it was losing all power.

Ford F-150 (2004-2008) :: 2007 - Overdrive Lost / Shifts When OD Disengaged

Lost overdrive. Shifts when o/d disengaged. Dropped pan, valve body and found that the servo retaining ring is still intact but the small clip for the center shafts of the servo was broken. Found it loose on the valve body along with a flat piece of metal shaped like half of a hexagon. 3 sided shape, approximately 1 inch each side. Like one 6 inch piece that's folded together. Don't know where that came from. Afraid to put back together without knowing where that came from. Was founded right next to the broken clip. 2007 f150 4.6 4x2 ....

I have a 2008 GC 6 speed transmission that has 55000 miles on it. When the engine and tranny is cold the transmission shifts very hard until it warms up. There are times when shifting from reverse to drive it shifts very hard. Also, the siding doors creak when driving over rough roads. Can they be adjusted?

Caravan/Voyager :: 2008 Grand SXT - Transmission Makes Tapping Noise When Shifts Or Downshifts

this has been an outstanding van, quite reliable. it has about 115,000 miles on it. Recently, I've noticed that the transmission makes a 'tapping' noise when it shifts or downshifts. every gear has that same slight 'tap'. the tranny shifts fine, smooth, but this sound worries me a bit. any chance this could be a u-joint issue?

Lexus GX 2004-09 :: Transmission Shifts Into Drive Twice

Lately, I've been having an issue with my 03 GX. It seems when the engine is cold and I back out of my driveway, when I put the truck into D, I feel the usual bump into drive, then it falls off and then a harder bump before I'm able to roll forward. If I don't pay attention and accelerate at the time the transmission seems to drop out of gear momentarily, the truck slams into gear and feels like I granny dropped it.

The truck is coming up on 120K. I've checked the transmission fluid and it is at the correct level.

Camry :: 2004 Auto Transmission Shifts To Neutral When Driving

My wife's 2004 V6 Camry is not happy. As you accelerate from a stop, the automatic transmission will go from first gear to second, and then sometimes just drop spontaneously into neutral. Because you are in the process of accelerating, the engine RPMs increase until you take your foot of the pedal. In the short trip to the dealership for testing, the problem seemed to reset itself when the car was fully stopped. Other times it just reengaged with the transmission on its own without stopping.

Each time the transmission disengages, another strange thing happens--the instrument panel goes bonkers. The speedometer needle drops to zero, but the tach keeps working. The ABS, check engine, and brake lights turn on.

The dealership had the car for several days and has only been able to scan codes indicating the ABS system and the rear wheel speed sensors. I'm skeptical--especially since the repair estimate is nearly $4,000! I'm taking the car to an independent shop tomorrow for a second opinion.

I can follow up with more details from the dealership's diagnostic report, but for now, all I can say is that the car has almost 100,000 miles and we haven't had a bit of trouble with it until now. I replaced the transmission fluid about 10,000 miles ago.

Ford Transmission :: E4OD Shifts Hard When Warm

I just rebuilt my E4OD transmission in my 1996 F250 7.3L it has all new clutch packs torque converter and a shift kit. When I first put itback together it would not shift out of second cleaned mlps and shifts threw all the gears now. I took it out on the road to test it and this thing ran great shifted smooth and quick could not askfor any better but when Trans temp gets around 140-150deg it shifts hard and od light flashes. I have ordered a scanner to read the codes but won’t be in till later this week. What I could check in the meantime.

Ford Transmission :: 1991 F350 - E4OD Shifts In And Out?

I have been hoping this problem would go away but it hasn't. I drive a 1991 350 diesel with Banks turbo and transmission module. When we first bought the truck it was only a few thousand miles before we had to have the tranny rebuilt. It was fine for about a year or two when we installed the Banks turbo and then after about five thousand miles the torque converter flew apart and ruined everything inside the tranny.

After this second rebuild it seems to be doing pretty good all except for it wanting to shift in and out of overdrive for no reason. I can have the cruise set on anywhere from 50-65 and when I start up a VERY slight hill it will downshift to third. I know that this engine has plenty of torque to maintain its speed up these small hills without downshifting so something isn't right. On this last rebuild our mechanic contacted Banks about the trans command and they told him to wrap the exhaust pipe with insulation to keep some of the heat off of the module under there and that seemed to work some.

(It shifts better than at first except for going in and out). Another thing that might be interesting is when it was first rebuilt this last time it had a problem with jerky shifts and the tranny light would come on. Our mechanic had to replace some sort of sensor in the tranny that kept breaking. He did this about three times and since he wrapped the exhaust it hasn't happened again. I hope I made everything clear for everyone to understand.

Ford - Ranger :: 2000 - Transmission Shifts Hard From Stop To Go

2000 Ranger autimatic, 2.5 lt 2wd, 155,000 miles. To my knowledge it has never had a tranny flush or the fluid changed. I have noticed last week that when you are taking off from a stop sign it jerks going into gear. This only happens when you are taking off all the other shifts are smooth. The transmission fluid color is redish-brown and doesn't have a burnt odor. I don't know where to start. Do I get a tranny flush, change the fluid or is it something else?

Ford Excursion :: 2003 V10 - Slight Slip When Transmission Shifts From 2nd To 3rd

I have a 03 ex with a V10. Just recently my trans has started giving me problems. Sometimes when it shifts from 2nd to 3rd I get what feels like a slight slip. Sometimes it doesn't happen at all. Feels almost like it is downshifting for a second. It also doesn't seem to make any difference whether I am hard on the gas or not.

Ford Transmission :: 1993 F350 - 4EOD Shifts Hard

I have 1993 F-350, 4X4, four door with a 460 fuelie and a 4EOD. That"s a bunch of 4's! I bought this pickup with 186,000 miles on it in 2005 or so, really just to haul fire wood and go to the dump once every 6 months. I don't know if the the tranny has ever been rebuilt. Nothing else on the pickup has been rebuilt. It now has 196,000 miles on it. In the past the tranny always shifted like a stock 4EOD. Kind of slides into the first three gears then into overdrive pretty solid. I took it out to go to the dump last week and it was just like always until it took it to taco party last night and it started to shift real abrupty. Doesn't matter how fast you go, it hits just as hard if you are on the gas or just casually cruising. It is hard in every gear. My first thought was that it may be low on fluid. When it is hot, idling in park after a drive I don't see oil in the little holes on the dip stick. I see oil on the dip stick but not in the little holes. Am I correct in thinking I should see oil in the holes? Actually I will see oil in the little holes when I first pull it out, then if i wipe it, put it back in, I see no oil in the holes. Engine idling in park of course.

Ford - Taurus :: Transmission Shifts From 2nd To 1sr Gear When Press On Brakes To Stop

I have a 1995 Ford Taurus when I press on the brake to come to a complete stop the transmission slips from second gear to first gear. But when I press on the gas and go from 1st to 2nd gear its a hard shift but no slipping. I checked the transmission fluid it was low and dark so I replenished the fluid and put in this slip and seal stuff in the transmission. What else can I do and how long do you think I will be able to drive my car until it dies completely?

Ford Transmission :: 1998 - Slam Shifts / Speedometer Quit Working

I have a 1998 e-250, 5.4 4EOD/4R100. The speedometer quit working and with that came hard shifts. This happened previously (only with a blinking O/D light that time) and I replaced the VSS and then the shift solenoid and filter in the transmission pan. That fixed the issue for about 3 days. There were no codes in the computer.

For a couple days the speedometer would not work until about 15-20 mph, then it would work and shift normally. Now there is no speedo action and the shifts are hard at high RPMs.

In the days leading up to this problem I heard a clicking in the dash, seemingly behind the cluster. Kind of like a turn signal but a bit fainter. Before I go and order a cluster...is there anything else I should be checking for? I have no warning lights, and as I said earlier the O/D light is not blinking. We're converting the van to a camper for our upcoming honeymoon and tracing this down is cutting into the buildout.
