Stupid 4L60...
Well a couple weeks ago when i went to go pick up my lq4 from the machine shop, i thought the 4l60 was laughing at me on the way home and this morning i was right. When i was at 10mph or under to stop, it would feel like something would disengage because all a sudden it would feel like neutral then engage again. Then when i went to take off i would have nothing with pedal movement then it would engage and id be moving. Its been doing that on and off for the past week or 2, and this morning it was doing it pretty bad with real soft shifts and slippage. so when i got close to the house i started to beating on it and it worked fine! So i took it around doing several full throttle runs from 20, it would shift great and firm and chirp second as usual and act fine for a few seconds after that then return to slipping and what not. Its lasted 9 months since it was built with sunshell, transgo hd2 shift kit, bands and what not. just sucks 
, does the problem while stopping and taking off sound like a converter?

I see that you have the trans go kit. Did you upgrade the forward and 1-2 plastic accumulator pistons? Almost sounds like one of them is cracked or you might have an issue with the forward clutch oil circuit. This would be an issue with worn stator bushings and leakage at the turbine shaft rings. Just a couple thoughts. Vince

Ill post it up when i find out. Last time he didnt show me the broke parts(stupid me), but this time im gonna tell him to keep everything he replaces. when you say turbine shaft rings are you referring to the converter?

well got the truck back today, only thing he found was the wide red band had a crack in it and he thought it was causing some binding issues, so went back with a borg warner high energy. No burnt clutches, changed 3-4 accumulator or regulator(idk what its called). Also went through the valve body and checked everything out. New wiring harness. Seems fine now but i still have a problem, when i manually shift down to third on the highway and go to put it back in fourth, it usually takes a few tries moving it from 3 to 4 to get it to go back into 4. Guess ill call him again monday....
