Thread: Tranny Temps

That in the norm. I think the tranny enters "hot mode" to protect itself in the 250* range. I see up to ~200* myself but rarely over.

i wouldnt get nervous until the temp creeps above 215*F.

Is it 50* warmer outside? There you go.

Mine used to get up to 200*+ in the summer so I installed a trans cooler from summit racing and when I drove it last summer it only got up to 170*-180*.

i have the gm aux trans cooler and both city and cruising they trans cooler is +/-10*F from the coolant temp at ~186*F with the 180*T-stat. i noticed in the warm weather such as at 75*F if i get on the car on the freeway for example, for a while the trans temp will pop up to ~207*F and the coolant will be at 200*F. thinking about throwing in the drilled 180*F but want a bit more mileage with the nondrilled 180 T-stat ^_^;

I have the same cooler as fst, and I don't think I have ever seen over 210° trans temps. Even in hot weather sitting at a traffic light. Now, I don't do a lot of city driving. But even the little I do, I don't see these high of temps. On an 80° day driving highway, I see about 160° trans temps. In the city, I might see 180-190°.

Over 210° is when I would start to worry. But that is just me.....but I do have 185k miles on my stock tranny *knock on wood*

^yea but do u get on it hard such as the freeway and from a low roll, if not it'll last for a while longer than mine did lol
i already killed one tranny but i dont want to on this one >_> lol

It's 90* here today and I never saw over 200* on my tranny or coolant. Uses the stock cooling config (through radiator) and I do have a 180* tstat.
