First post from a newbie...........

I have a custom 50 chevy with a C4 vette driveline, bought it this way with no info from the owner. I wanted to ID the tranny because of changing out the shifter. One guy says its a TH400 beacause of the shape of the pan, another says its "one of those TH375 performance trannies" a TH350 w/added performance parts. Has anyone else heard of this TH375? The pan does appear to be a 400 pan, after looking it up. I have a B/M shifter now that is ancient and hard shifting so what shifter do you recommend for this application. I like the lokar stuff and the newer ratchet type shifters too.

Thanks for any info

They were a low performance 400. Less plates in the clutch. If you look on the bottom of the tailshaft housing it should have a cast 375-thm. The output shaft spline and yoke are the same as a 350 or a powerglide.

Thanks, so any shifter that fits a Th350 or Th400 will work? If so that gives me alot of options. Anyone with a favorite for street driving? Floor mount

Many are adjustable but I would think using one for a 400 would be the way to go.

For performance you don't want a gentle shift. You want it to shift as hard as possible.

A shifter won't make the trans shift any different. Not unless the thing is getting stuck between gears. Then it will burn up the trans.
