Turbo Hydramatic 375 Transmission.
Came across a Turbo 375 transmission in a friend's garage. Had been in a 1974 Grand Prix. Supposed to be in good shape and can buy it for $50. I'm not familiar with this 375 and wondering if it is worth buying. Is it as good as a 400 or is it weaker? Is there any demand for the 375? Thanx.

I wouldn't. Is it as good as a 400 or is it weaker? Weaker, a mix between the TH400 and TH350. Has less clutches than a TH400 and a TH350 output shaft. Is there any demand for the 375? No, not really. I'd say pass, good working used TH400s can be had for nearly the same money.

Thanks b-man!
That's exactly the info. I needed. You saved me $50. I suspected this since you hardly ever hear of anyone running a 375. I understand why now. Thanks again.

Probably a small bit weaker than a 400. Internally it is identical to a 400, but as B-man mentioned, has fewer clutches in the clutch packs and a smaller (TH350 size) output shaft.

Easy enough to add different clutch packs and the larger output shaft/tailhousing. Depending on the application, the 350-sized output shaft could make a trans conversion easier.
All this assumes we're NOT talking about a 375B, which is a HEAVY DUTY version of a 350. |

Sure its easy to change the clutch packs, either by machining the drum and piston or getting both from a Th400.. Some of which had 6 in each, but most often had 4-5 frictions and steels in them. The drums are different between transmissions regarding how many frictions and steels you can put in them. |

I had a TH375 in my hot rod behind a 400 for ten years. Pulled the motor and tranny out of the hot rod and put it in my shop truck four years ago.
Fourteen years of abuse and never a hiccup...I'm not complaining. -Abone.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
