Trans lock up "hunting"

[orangecar]

Rebuilt my trans with all CK's good stuff, shifts great, only problem , the converter lockup wants to go in and out at 40 to 60 mph, some times acts like it doesn't want to disengage when coming to stop soon enough. Used a new GM 2004R selinoid, would using the 700 4R selinoid be better, or do I need to get Turbo tweak to adjust the chip. Thanks.

I am having a similar issue. Bought some toggle switches so I can manually bypass the computer. My issue seems to be that when going around 40-60 your foot is very light on the gas pedal and when the tps reads below a certain # (not sure what it is) it unlocks the converter. Then when I give it a little bit of gas, it locks back up. Very annoying. Especially when you're in that threshold area and you have a higher stall!

Check out my thread, maybe it will help you...
