Transmission Temps I just wanted to get an idea of what normal trans temps are in these cars. I installed a huge tranny cooler last summer after buying my car and reading about all trans problems they seem to have.
Up until last week, I never had a way of reading trans temp, but now I have a scan gauge that does show it. So far, here is what I've been seeing:
In town, outside temp 70 degrees, trans temp is 150-155.
Flat steady highway, outside temp 70 degrees, trans is 155.
Long steep grades like the I5 Grapevine and I10 Chiriaco Grade in 70 degree temps, the trans runs at about 165-168 at a 75 Mph cruise.
I know these are good, low temps, but I'm curious to know what others are sewing.
Can you post some temps with driving situations, and whether or not you have a cooler?

So, from what y'all are saying, the temps I'm seeing are on the low side, which is good, because the tranny doesn't show any sign of problems. I know they can go suddenly, but I hope the low temps and generally good health of my tranny means it lasts for a while.

Real low from what most other experience. Mine ranges from 185 - 225 depending on the time of the year and how far the ride is. These transmissions suck. Your torque converter still must be good. Those seem to go fast and if you don't catch it in time it makes the whole trans. bad. You'll probably experience high temps at some point.

Should I go with an aftermarket converter now, before the stock one goes? I've wanted to go with a tighter converter to get rid of the factory slop. This would be a good excuse to replace it
Well replacing it is up to you. Here is a good place to start. The one all the way at the bottom will fit a 245mm & 258mm flexplate. It is an actual 245mm tc and weighs about 6 lbs less. With less weight things tend to last a little longer. I just went with one of thier reman's from Precision.

Well the factory stall is between 2650 - 2950 already. I am sure you can purchase whatever stall you'd like. You'll have to e-mail Dave and get some info from him. I'd stick close to stock because the remans and aftermarket convs. are usually a lot tighter than the ones the car comes with. My Raptor is a pretty tight converter but the stall is a 2800. (These go bad fast, so don't get one...) Much tighter than stock even know the stall is quite close.
A shift kit will make the trans slop be a lot less too. If you are going to do the t.c then do a shift kit too. There is a TransGo shift kit thread on here somewhere.

I don't have a trans temp gauge on mine, but I went with the finned aluminum pan by ZZP. Plus it has a drain plug.
According to Intense Racing though, coolers don't seem to help these transmissions from breaking. They stated that hard parts are what breaks in these. But, I do figure every little bit helps.
