Tranny Temps

I've got a basically stock 04 compg. since the weather is getting hotter (70-75*) im seeing my trans temps skyrocketing. Normal city driving im seeing 186* on average then if I give it a little gas it will jump up to 201* sometimes. This winter I was a constant 156* for the most part. Is this normal? I understand the trans may run hotter since the weather and street is but I get nervous when it gets near 200*. I'm running dexron 6 with a gm filter. got it changed about 7k miles ago. I never burn out and rarely go WOT. 32k miles. Thanks.
 


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.
 
with my3250 stall i see temps around 220 if i'm doing alot of city driving and around 190 on the highway
 


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.
