When i drive and just keep accelerating through the gears there is quite a jerk when the auto shifts. I've been able to go around this because i know when its going to shift and let off the accelerator, all been working well. I just wanna fix i now beofre it really gets bad. My timing belt broke a couple of months ago before this started happening, and was replaced at the local shop(timing is beyond me). I recently went to ammco to get the tranny flushed and to see if they could find the problem. The couldnt fiqure it out and there were no codes. Could this be improper timing? or maby something else.

Thanks in advance,

Chris

Does it slip. or just shift hard?

it just shifts hard. theres no slip.

Is it shifting hard from 1 to 2? If it is you might have a sticking 1-2 shift valve. Or if I recall correctly I think there was a TSB for removing/adding ball bearings from the tranny oil passages that could affect shifting (don't remember the correct info, might be off a little).

Well this should be a no-brainer.... but have you checked the fluid level?

ya i've checked the fluid, i had it power flushed by ammco not to long ago too, and they said it wasnt the tranny. It jerks shifting to all gears, but 1-2 is the roughest.
