93 4L60e problems occurring irregularly

[cjman250]

Truck is a 93 2wd ECSB 350/4L60e

problem i am having is that sometime when my tranny goes into OD, when i let off of the gas, it feels like its jumping. Feels almost like my truck is getting rear ended over and over again. Stops doing when i shift out of OD. It doesnt always happen though which is making me wonder. Any Ideas? I appreciate the help.

If your truck is a '93, it probably has a 700R4, not a 4L60E.

I wish I could be more help with the problem though.

4l60e was in some trucks in 1993

92 was the first year of the 4L60(no e) which was basically the 700r4. 93 was the first year for the 4L60e

Oh. Huh, I didnt know '93 trucks had 4L60Es. I knew the 700R4 was a 4L60 though.

Can you tell whether your torque converter is locking/unlocking? Both in OD and 3rd.

Wild ass guess, but a bad throttle position sensor will cause your auto to goes nuts intermittently.

How are your engine and trans mounts

Have you had your truck checked to see if you are throwing any codes?

Engine mounts are fine, I'll have to get under there and check trans
