It is hard to tell from the brief description you gave, however there is a modulator valve on some transmissions that will cause the jerking, or the tcc on some other vehicles. If you supply me with more info i can give you a better answer, but those are two things to look at.

I'm getting code po894 for my 09 chevy express van 6.0L. Engine light is on and transmission jerks when going from 1st to 2nd gear, but only when engine warms up a little. Doesn't happen when


This one could be any of them. If you tackle this yourself start with the cheapest and move to the most expensive. The other way is to take this in for a diagnostic, pay them for that, and then fix it yourself knowing what it is for sure.

I have a 1998 626 Mazda transmission fluid overfilled


It could, because as the fluid get warm it expands. As it expands it might not flow thru the system as it was designed too. You might check your motor mounts also. I had a mini van that i thought the transmission was shot. It would **** and bounce. After getting under it I found 2 of its motor mounts were broke. When I fixed the mounts the jerking and bouncing went away.

My car is a 2002 Volkswagon Passat. Just of recent, it jerks when I engage the gear from park!!


Check your transmission fluid level on the transmission dip stick while the engine is running. When fluid is low it results in a snatching at gears especially when engaging 'drive'. Add the correct fluid (check with VW on the correct type for your specific car) via the dip stick tube. Do not fill beyond the maximum. If you do not correct this the constant snatching will eventually cause the splined end of the input shaft to shear off and this will be an expensive repair.

My van is jerking when shifting from first to second gear and vice versa. Most especially in the morning. Please advise me for the solution. Thanks.


When is the last time you changed your automatic transmission fluid? Modern transmissions require regular fluid changes or they start to malfunction , generally shifting problems. Try a fluid change with any luck the transmission will go back to normal operation.

2000 Pontiac Montana... Turn on... Good. Drive down street... good. Accelerate... Auto transmission jerks or jumps into next gear. Check engine light is on. Autozone told me o2 sensor was bad. Will a bad...


No, O2 Sensor would make your van to be none fuel efficient at least or won't change anything if it's the O2 Sensor or Bank2 ( It mean's the 2nd one, the 2nd one is a dummy.. it just read what's going out from the catalytic converter and tell's the computer if there's a change since the reading of the first 02, so the computer see if or not the catalytic do his job ) For your Jerking and Jumping problem.. those Gm Van has alot of transmission problem and maybe your transmission on a way to take vacancy or it is just missing oil ! Check Oil first, for that do that when the Motor is Cold, Start you Van Leave it in "Park" Position, Pull the Dipstick of your transmission ( Should be the Red one ) clean the end of it with a Rag and put it back, pull it a gain and check if the oil is in the reading, if not add the missing oil while the motor turn's, and recheck it until it's full ! Otherwise if the dipstick show's Full, Here's a tip's go to your local autopart's supplier or store that sell's car product such oil's, coolant ect.. ! Buy a Bottle of : Lucas Transmission Fix, Remove the Transmission Plug, and remove about the half of the oil ( Not the Whole amount of oil, only the half it's important ! ) and put the plug back well tighten, pull the dipstick and add oil from the dipstick tube with your bottle add about the half of the bottle, start your van, check the oil level if it still missing some oil add the amount it require to be full ( While Motor is Turning ) ! Important do not Overfull the transmission ! This Should Work or not, if not.. I would say you need to Replace your Transmission, What I told you is about 15minutes of your time and a couple of dollar ! Best thing is to bring your van to a Transmission Shop they will tell you the problem !

Transmission fluid levels


just add to the cold line when cold... when the car warms up the water will rise close to the top with out overflowing.. And on a side note.. engine "jerking" can radiator capacity have almost nothing to do with wach other unless you have a blown head gasket..

3.8 Liter Transmission


Would need to consult a band/clutch application chart to determine exactly what is going on,but one of the major components inside the transmission is obviously not working correctly.Have the vehicle scanned for diagnostic trouble codes and the definitions.
