Twildman chip and shift hunting?

[orion_134]

I bought a used chip from a owner who had it installed in a similar-modded truck to mine. It has a shift-hunting at 34-37 mph at part throttle light/no load, it doesn't do it with the stock tune. Any thoughts

Just a thought but it is the converter going in and out of lock-up. I never had any issue's with it on mine but I did have a fairly stout tranny and I did the torque converter lock-up mod also so I could control TC lock-up at the flip of a switch. Cheers, Patrick.

It is tc lockup, and I think 35 mph is when he programs it to lockup vs. the stock 45ish mph...but the hunting isn't cool. My tc is a built factorytech as is the accumulator body. The solenoid pack has just been replaced when the trans was rebuilt.

hmmm.... Maybe it would be best to put in email into Tony I'm sure he would know exactly what is going on. I know what your talking about but kinda lost because it didn't do that for me. Could you please let me know what you kind out though. Thanks, P.
