Re: [Chrysler300] torqueflite trans.

["Steve Galezowski" <stevenlulu@xxxx>]

That's what happened to me (ie kickdown adjustment problems not transmission
failure). I don't know the technicalities but I had the tranny rebuilt to
high performance specs. and at the same time installed an aftermaket
manifold and carb. with different linkage connecting points. When the tranny
was reinstalled the kickdown was screwed up. It took a lot of fussing by my
mechanic to get it right. But now its great. The tranny shifts firmer than
stock and it holds a gear longer before upshifting and as mentioned in a
previous e-mail the full throttle upshift is at 78 mph which is also the
speed over which the kickdown does not engage. So it was a bit of a headache
but worth it especially with a beefed-up motor.
