THM375B - This trans is identical to the THM350, but is considered a heavier duty transmission. Gear ratios on these units were 2.52 1st gear, 1.52 2nd gear, 1.00 3rd gear.

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.
Gear ratios on these units were 2.48 1st gear, 1.48 2nd gear, 1.00 3rd gear.
