Be careful to not be fooled into thinking a TH250 is a TH350. The TH250 looks almost identical to the TH350 externally- same size, same oil pan. Unlike the TH350, it has a band adjuster stud and lock nut on the passenger side of the case near the cooler lines. The oil pump does not have the intermediate clutch piston, clutch pack, and associated direct clutch drum. Some 1974-'75 Chevrolets (Camaro, Nova, Monza, Vega) equipped with the Vega 4 or inline six were equipped with the TH250, which was a replacement for the discontinued Powerglide. The TH250 was revised in 1979 as a TH250C with a lockup torque converter and was commonly used with the Chevrolet 90 degree V6 (200/229, excluding the 4.3L) or Buick 3.8L (Series I) V6. The revision of the TH250C was in response to the failure rate of the TH200 when it was used with V8 engines (Chevrolet small block and/or Buick/Oldsmobile/Pontiac V8.
