THM375B - This trans is identical to the THM350, but is considered a heavier duty transmission.

THM375 - This transmission is a derivative of the THM400 sharing the external appearance of the 400. It'll be marked 375-THM on the bottom of the tailshaft housing. It's a light duty version of the THM400, has ABSOLUTELY NO RELATION to the THM375B, and was found in 1972 to 1976 full-size cars. The Turbo 375 was modified to accept the Turbo 350 driveshaft yoke.

Welcome to ECC/NECOA Lee!

:mrgreen:

Welcome Lee. We always need another 3rd gen in the group. How do you like that 400 SB??

the pictures i will put on as soon as my wifes digital camera gets here. as for being sweet :lol: its far from it. im still in the middle of redoing what some idiot thought was cal custom. the same idiot also thought they knew how to work on an automobile. i just moved so all i have had time for so far is to pull off the NOS stickers he put all over the body turn the fuel filter around general B.S like that. this weekend im putting a bench seat in and putting the shifter back on the column getting rid of the buckets and floor shifter thats half ass installed at the moment......how do i like the 400 sb actually i love it 1 of the few things that was done right found the tag from a local rebuilders on it stoped in and talked to the builder he shares my oppinion of the previous owner mainly that he should stick to soap box derby cars., but at least i know the build is sound.

I have never heard of a 375, that is what I like about this board, I learn something new all the time. So basically the 375 Tranny was built to deal with a higher torque use, like light duty towing?

Are the gear ratios the same as the 400 or the 350? Does the 375 share the same type center shaft support as the THM 400, internally.

I want to add my welcome to you too, Lee, and also echo ElkyPete's comments about the amazing level of knowledge here in ECC (not me though :huh:)
