Ive got a th350, ran good when i pulled it out of my old firebird, 4 years later stuck it in a camaro, now it grinds when i shift under hard throttle. Started behind a decent 400 has a shift kit with 2400 stall, now sits behind a almost stock 360 with a 1800stall.

 

That's a hard one I don't know but could the linkage need to be adjusted maybe it is holding it between gears just throwing an idea out there.

 

Ill check into that. Thanks

 

OK and don't forget to keep us updated maybe we will need to help you more.

 

I dont have the kickdown cable hooked up, would that make it goofy? Cable on the trans is good. It shifts good still churps tires into second, just grinds slightly.

 

I think you need to get everything hooked up and then let us know what you got'
