TH400
Three Speed Automatic
The GM Turbo Hydramatic 400 has the reputation of one of the best automatic transmissions ever made. This strong 3 speed automatic can easily handle a high horsepower engine. The only issue with the TH400 is it's relatively tall gearing. There are kits to lower the gearing but they are expensive. The TH400 is also a long transmission at 24.37 inches.
The TH400 was the first automatic transmission to come in a CJ. It was available from 1976 to 1979. It only came in CJs that were equipped with the QuadraTrac 1339.
Gear Ratios
1st – 2.48
2nd – 1.48
3rd – 1.00
Reverse – 2.07
