Stats: 1990 suburban 350 w/ new 700r4 tranny Recently rodded stock radiator w/ 180 t-stat. 28000gvw tranny cooler. We are on the road right now heading to Mexico we are now just north of Vegas. The temp gage is climbing above 210 and the tranny temp guage is up near 185-190. This is to hot for us to continue on south to Cabo San Lucas. The tranny temp sender is mounted in the pan. Weve been told by Bow tie overdrives that the tranny should not get hotter than 165 or severe damage may occur. Do you agree? Everything is new on this rig but the engine which runs very strong. The engine temp is fluctuating widely right now, where my other suburban never gets hotter than 190 with a 180 thermostat. The heat exchanger or any other part was not replaced when the radiator was rodded. So we are considering stopping in Vegas and buying a new radiator (what else could it be?) The shroud is on correctly. The fan clutch is original but we dont know how to tell if its bad. Thanks.
