The ST-300 was also produced with a variable pitch torque converter. This converter could change stall RPM with an electric solenoid inside the transmission that was activated by a switch usually mounted on the throttle linkage. | The ST-300 was also produced with a variable pitch torque converter.

| + | This was a low cost Powerglide-based transmission that used a manual valve body. It had to be manually shifted into high and down to low. It was sold under RPO MB1, and cost about $100 less than a Powerglide. It was available with 4 cylinder and 6 cylinder engines. | ||

| − | the | + | the TH350 trans was built in 5 different lengths. Two were 4x4 applications. Tail housing lengths of the two wheel drive were 6 inch, 9 inch and 12 inches. The 12 inch length is not very common. It was used mostly in Buick AND Oldsmobile station wagons. |

1987-up 3L80HD is the HD version of the TH400 found in light trucks. It has 27 spline output shaft and is 34.5" long overall in 4x2 version. A common tag code on these is '''LJA'''. Found cast on the bell housing in medium size letters is 'HD'. The TH400 transmission was used between 1964-1990. 1987 was the year the transmissions were renamed using the alphanumeric designations. | 1987-up 3L80HD is the HD version of the TH400 found in light trucks.

| − | 4L80E is a full electronic controlled and shifted transmission with similar design and strength to the T-400 trans. Early 4L80E and | + | 4L80E is a full electronic controlled and shifted transmission with similar design and strength to the T-400 trans. Early 4L80E and TH400 shared some parts that could be swapped. In 1996 the 4L80E has some design changes in lubrication circuits. You must be very careful when replacing gear train parts in late design 4L80E. |
