But unlike the T-350, 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. The 1979-'84 T-250C used an oil pan with an X-shaped stamped rib (T-350 oil pan is smooth). Usually found in 1974-'75 Chevrolet Vega/Monza (including H-body clones), 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 T-200 when used behind anything other than a 4 cylinder (coupled to the Buick V6 3800 engine or Chevrolet 90 degree V6 exc. 4.3L) until 1984 (same as the 1974-'75 design but incorporating a lockup torque converter (same as T-350C), a lightened sunshell with 3 or 6 drilled holes (sometimes used in performance applications to decrease ET due to its lower rotating mass), low/reverse piston (with 8 cutouts), and auxillary valvebody (shared with the T-350C). T-250C mostly found in G-bodies (third generation F-bodies came with the T-200C or 700R4) and some B-bodies until the 1984 model year when it was last optioned. |

This 7-3/8” long extension housing can eliminate transmission crossmember modifications when replacing a T-400 or 2004R transmission with a 4L60 assembly.<br> |

GM uses an adapter which threads into the case cooler ports and is sealed with a washer. The adapter converts the thread to inverted flare for hard line usage. The cooler ports on the T-350 are usually a female 1/4"-18 NPSM (National Pipe Straight Mechanical (NPSM)) and use a metal washer/seal. The NPSM threads will fit a NPT (tapered) fitting, but if a tapered fitting is to be used, be careful to not over tighten it. | GM uses an adapter which threads into the case cooler ports and is sealed with a washer.
