Sounds like it has a shift kit in it.

Seriously? You're asking without providing ANY information other than a TH-400. Size of rear-end, open vs posi, size of engine, RPM when shifting, WOT, radial vs bias-ply, type of car. What you are asking is nearly impossible to answer without appropriate information.

I'd agree if it chirped in a basically non-acceleration profile.

Well a 455 with bicycle-size tires on back should spin them any time you get on the throttle.

Some of the factory performance TH400 had a pretty aggressive valve body calibration. Even those had to be mild enough that part throttle shifts wouldn’t scratch the tires on every shift. It sounds like someone installed a shift kit.


Are you wanting to tame the shifts?
