Malibu transmission question

[TURNA]

All depends on which TH400 you have

 

[Ratchet]

I’ll measure it once the transmission shop gets it back to me.

A TH350C should hold up no problem and it will lower highway rpm 300 rpm. Look for the band adjustment stud, a TH250C may not survive. Why would you want a TH400?

The TH250c, unless my memory is shot, uses the same pan as the TH350 & TH350c.

Physically, they will interchange. A production 350 pan is smooth, a production 250 pan has a bunch of ribs embossed in it.

Yes but will say METRIC on the pan s well as the band adjustment screw

TH200 says metric, TH250 does not. The band adjustment is the big tipoff to a 250 vs 350

I am using the TH400 because I already had it. I sent it to the transmission shop to check it out because it had been sitting for a couple of years.

From the top side you can tell if it's a turbo 250/350 as it will have a 3/16" vacuum hard line running from the vacuum fitting on the right rear of the intake manifold.
