auto transmission w/36k...when taking off from a dead stop or a slow roll the tranny stutters then jumps into gear. some say that is normal for a 4spd econobox car but im not so sure. if you give it more than 1/4 throttle from take off it doesnt do it...only if you are driving light footed. also this is only from 1st to 2nd gear. every other shift is flawless IMO
any ideas? the balt will soon be my younger sister's and i dont want her taking on any issues i cant fix before hand
mine does the same thing, illtry to take off slowly and ill start to roll and once i give it more gas( just the littlest amount) it jerks forward rather quickly and you can feel the engine shift funky.
not to sure wtf it is

Sounds like something may be slipping slightly internally. Could also be a minor TCM malfunction. If first to second is the only problem, and it is intermittent, personally I wouldn't worry too much about it. If it is really bothering you, I would take it to a dealership and pay for an hours worth of diagnostic time. I don't have that much experience with transmissions, so unfortunately that's all I can give you.
just saw this post...if you are stock take your car back to the dealer. Tranny shouldn't shift like that. Could be caused by what ever is causing your P0171 code (fuel trim system lean).
Depending on the temperature of the coolant it may or may not be more severe. Do you notice if the tranny does this when the engine is cold or hot (normal operating temp). The temp could help isolate the problem since the ECM runs in "closed loop" while cold and "open loop" when warm. In simple terms, depending on engine temp the ECM controls the fuel delivery with different sensors.
Since the shifts are controlled electrically It also could turn out to be a problem with the TCM -- can you read the codes? Are there any other codes showing? Not on your DIC in the ADL with a code reader.

thx for the response. i scheduled a dealer visit for early next week. doesnt matter on the temo, it is 100% of the time so i thought it was 4cyl/auto tranny thing. i do not have a code reader, this was from an autozone reader as it popped up duing a 300 mile trip last weekend.
