Hey guys I highly recommend the UltraGauge to accurately monitor the coolant temps, and it has a alarm setting. Click the link in my sig. Before I did the fan swap I did my entire cooling system and installed the Stewart water pump. Also changed the transmission oil & filter.

Last week we had a heat wave here in the west, the temp was 117 degrees for several days. My coolant temp always runs at 192.2 degrees (89 C) on the highway normally, that week it was the same. Sitting in traffic it would be around 195-199 degrees (90-93 C). The Electric fan worked great!

My fan will come on at low speed when you turn the AC on. Without the AC on it comes on low speed at 195 degrees (90 C) as it reaches 199 degrees (93 C) it speeds up.

Question concerning turning on the fan manually. Not sure if its possible, this was addressed on here previously. The fan has constant power to it and the DME controls it by certain ohm reading. I do believe that's correct.

How are you guys accurately monitoring the transmission temps? Are you sure it's accurate at 224 (107 C)?
One thing you might check is the transmission Tstat underneath the expansion tank, I do believe its rating is 176 degree (80 C). My Tsat was broken when I did my cooling system, my car has 118,000 miles. They are $95 from the dealer.

I am attaching before and after INPA monitored temperature. Could this be that my thermostat is not functioning properly?

where is the dash temp needle when this is occurring?meaning, if you weren't monitoring with software, would you be able to tell?

something not right

The dash temp needle? If your referring to the temp gauge on the dash board, its actually on the middle. Im just wondering why the my gearbox temp would reach 107 C and still rising? Could it be that my INPA software is not properly calibrated because before starting ( cold engine or at off engine ) the reading was already at 46 C. I stop the engine at 109 C after driving for about 15 minutes. Though the swap give a big improvement on the car performance, i just want to know what is the normal temp for gearbox so i would be aware. Or could be my thermostat?

well, since bmw didn't put a tranny temp gauge in dash, i would assume, if the water temp is good so is the tranny temp

it all runs thru the same radiator

Normal operating temp range is 175 to 200 degrees.

True but if the transmission temp Tstat fails ( stuck closed ) this would be why the engine temps are normal and the transmission temps are high. The transmission temps are generally going to be higher sitting at idle anyway Mechanical fan delete or not.

Fahrenheit. You probably wouldn't get a code until the Transmission was having serious issues. When I did my cooling system I replaced my Tstat, it's under the expansion tank.

Update : I change the transmission fluid using Liqui Moly 1200, drove the car for 15 min (while laptop connected to the CAR using INPA ) results is still the same at 109 C this time and still going up but at very slow rate. There is no error code so far.

To :WOLFN8TR and WASP9166, did you measure your tranny using INPA? These would be my next course of action 1) Place the old mechanical fan back and observed if i get the same measurement ? if i get the same measurement, then i guess its normal if not then something is wrong. The Swap may not be compatible with my Car 2) or I change my thermostat first before reverting to the mechanical fan? 3) Or let the car run at idle for a long time and observed where the gearbox temp would stabilized ( or would not ) but its too risky unless we know the critical temperature values so i could stop the engine immediately. 4) or verify it with another program. Appreciate all the inputs i would get from this forum. Thanks

No I never used INPA to measure my Trans temps.

I would either replace the Trans Tsat or go back to the Mechanical fan setup and recheck the temps.
I replaced my Trans Tstat because it was the original, (8 years old) when I did my entire cooling system.

Sounds like the Tranny Tsat or your cooling system isn't working properly. Funny how the trans temps are higher now with the Mechanical Fan installed.

Actually, i think bought version could have reach the same temperature , i just didnt drive the car long enough when i had the Electric Fan. I search the forum and they said bought temperature ( engine and transmission ) should be almost the same. Tranny Tsat or cleaning the Tranny Cooler ? Do you know how i can clean the cooler ?

Further updates...Electric fan installed....Gear Temp still stable at between 119 to 127 C.....I recommend to change T stat and clean cooler or do the swap when your about to change your T stat or clean your cooler. Highly recommended swap.
