It is an option, however. Some TH350 transmissions came with steel transmission cases in older military tanks and trucks; they would be best for mondo horsepower applications such as 1500+ hp cad engines. |
| − | + | But the TH400 remains the "go to" transmission for many Cad engine applications; it's affordable, tough, and came as standard equipment behind many Cad engines from the mid-'60s onward. | |
