| − | {{Note1}}Be careful not to mistake a TH250 for a TH350. The TH250 looks almost identical to the TH350 externally- same size, same oil pan. But unlike the TH350, it has a band adjuster stud and lock nut on the passenger side of the case near the cooler lines, similar in design to the Powerglide. Usually found in 1974-'75 Chevrolet Vega, Nova, Camaro when coupled to the Vega 4 or 250 inline six. Reintroduced in 1979 as an option for GM A, B, F, and G-bodies in response to the failure rate of the THM200 when used behind anything other than a 4 cylinder (coupled to the Buick V6 3800 engine or Chevrolet 90 degree V6 exc. | + | {{Note1}}Be careful not to mistake a TH250 for a TH350.

TH250C mostly found in G-bodies (third generation F-bodies came with the TH200C or 700R4) and some B-bodies until the 1984 model year when it was last optioned. |
