I had the transmission fluid and gasket changed now it jerks when stopping why

check fluids ---possibilities --trans fluid low -trans needs filter change-- failing trans--abs problem---if equipped 4wd problem --module -transfer case

First thing is to check your trans fluid level. When checking it, do a inspection of the fluid. It should have a nice red color. If it looks brownish, and smells burnt, it needs to be changed. In addition, when was the last time the filter and trans fluid was changed? Over the years, the vecosity of the fluid breaks down, and causes the valves in the transmission to stick or get sluggish. One trick I had seen used BUT I am not recommending you use it, is to get about a pint or two of k-1 kerosene, and with the engine running, pour it in the transmission, and run it through the gears, and then drain the oil and replace the filter. The kerosene cleans valves and ports in the transmission.

just as precaution, have you been changing the trans fluid as recommended. Start off simple, check the fluid level, change the fluid and filter if due. Read the owner's manual for how to check the fluid level. Check for any loose wiring connectors that go to the trans. IF this is no help. Get to a reputable trans shop.

You do not say if it is an automatic or manual transmission (clutch). I will assume auto. This could be several things. It may be something as simple as low fluid or possibly the transmission filter needs to be changed and the old fluid flushed out. Or the transmission could be starting to go bad and would need to be rebuilt or replaced.

My 07 uplander jerk hard into gear when I take off from a dead stop is it because my transmission is over filled

most likely a TCC seloniod.

i would atleast change the trans fluid and filter.

Jack up the van and securely support it.On the left side of the vehicle is the transmission , remove that trans fluid pan(on the driver's side)pry off the old filter, let all the old fluid drain out.Clean off the gasket mating surfaces, then reinstall the new trans filter.Install gasket sealant and torque pan bolts.Lower vehicle on level ground, install two quarts of trans fluid, then recheck trans fluid in the correct gear, I hope I could help!!!!

This is common problems to the transmission when the fluid is getting to dirty and the transmission fluid and filter needs to be replaced. The transmission fluid and filter should be replaced every 45,000 miles to ensure there is no dirt causing the shift servos from binding. The other thing to is that when the transmission fluid get's to dirty, the fluid gets thicker. It retains fluid retention which can cause conflicts in the transmission sensors. What your experiencing is, your transmission is not shifting back to first gear and sticking in to 2nd gear. When you get on the gas peddle, the transmission sensors realize that it needs to be in 1st gear, so as the engine's RPM goes up and the transmission drops back to 1st, you get the jerking condition which will in turn cause you a $2,300.00 transmission replacement. For now when starting off from a stop, let the engine creep forward on it's own first to ensure that the transmission has shifted in to 1st gear. Then get on the gas peddle lightly till you have the transmission serviced. $100.00 transmission service is better then $2,300.00 transmission replacement. Good luck and do not have a transmission fluid flush, just filter and fluid replacement.

check trans fluid level, change trans fluid and filter, check for broken or loose connections on tranny, check speed sensor on trans,
