7. To adapt the LSA to the TH400 we used a TCI flex plate (PN 399756) and torque converter. We initially built the truck with a small 2,300-stall converter (foreground) but eventually swapped it for a 1,800- to 2,000-stall converter (back ground, PN 241502) after seeing very high transmission temps, which could be due to the smaller diameter and higher stall. We have since been advised that TCI PN 241602 would be the best for our application since it is designed for heavy torque loads and trucks.
