Trans Temp gets hot under full throttle, whats wrong???
Trans Temp gets hot under full throttle, whats wrong??? I recently had a 4L60E Built locally and a Transmission Specialties 4000 stall lockup converter put in as well. Im running a B&M 28000gvwr Supercooler as my tranny cooler. I have the gauge tapped into the pressure test port.
When I cruise the car around town and highway, I see temps of around 180 degrees. I took the car to the drag strip last week and my transmission temperatures skyrocketed to 250(gauge only reads 250) degrees. My local tuner also saw the temp reach that during dyno tuning.
Could my converter be slipping under full load? The transmission feels good at wide open throttle, doesnt appear to be any trans slippage. But I'm not a transmission expert so I dont know for sure. I am thinking the TC is slipping pretty bad. Car also dyno'd about 20-40 rwhp less than similar cars around here.

How should I route my coolant lines from transmission to the cooler. Feed on bottom and return on top? or vice versa. I think I have mine right but I wanna double check.
Ok first off, did you have a guage on it before the rebuild/stall? if you didnt, then theres nothing to say it wasent doing it before and you just never knew.
2nd, is the tranny fluid still going through the radiator? if it is then the motor is prob heating the fluid, not cooling.
3rd, get a bigger fluid cooler. Big stall=big heat
4th, what is ambient temp? and also, is the tranny doing anything else, other than getting hot? the pressure port reads roughly 20 degrees higher than actual temp.

Ok, The cooler setup isnt running through the radiator, just the 28000gvwr B&M Supercooler thats mounted in front of the radiator(no Condenser). Coolant runs at 190 degrees.
The car is a 1990 Firebird with an LQ4 in it. It had a TH400 with the same gauge hooked up to it. I swapped to the 4L60E with 4000 stall this spring and just got it running when I noticed this problem.
The torque converter locks at any speed over 40mph on mine
