What are the normal operating temps with the engine coolant and transmission fluid ?

 

Our stock T-Stats are 193 degree's and 200-210 is about the right operating temp if I remember right.
The T-Stat is fully open at 221 degree's I have read.

I am not 100% sure but I think trans fluid temps for the 4R70W is suppose to be between 160-175 or so and peak around 190-200 depending on conditions.
If you run it really hard then you could spike much higher (250+) and possibly run into killing the trans.

There are several cooling kits out there to help cool it.

 

About what I thought thanks Neo Tokyo.

 

Any time.
