Trans Temp

[Got Diesel?]

I have a 1997 F250 with a 5 speed manual trans. i drove from hagerstown to bwi airport (80mile one way drive i believe it was) doing approx 70 to 75 and twice i had it going about 100 and my trans was a steady 190. the hottest it got was 200 degress. i wasnt towing any either. i was wondering what the safe temp range is for the manual trans in the obs truck.

Hmm honestly Im not sure, but someone will chime in with a good answer for you. Generally a manual will run cooler then an auto trans.

Oh and those temps are fine that you were running. Once you start hitting 200 and above thats when you start to worry.

I always thought manual transmissions ran cooler then the autos, but not in my case. my brother has a 1999 f350 auto and when we went to myrtle beach in august, his truck stayed around 180 the whole trip. now that he put a 6.0L trans cooler in this truck, his trans temp hasnt gone above 150. maybe thats what i should do..

I was just towing my 8000 lb trailer through the smokey mts. and panicked when I hit 196. No problem though my egt's were getting up in the 1150 range and my commander started defueling my chip. That was the first time for that and it worked great.

if you want to put a secondary trans cooler i would recommend one with a built on fan.... that way you can turn on the fan when you need too... they are a lil more expensive but well worth it.... here is one installed on my truck
