TH350 Cooler line pressure

Hi

I'm getting readings of 20psi at tickover and 50psi when revving the engine with cold oil, does this sound about right?

The transmission gets hot on prolonged use yet the cooler seems to work well, the hose going in is too hot to touch but the return is just warm.

Thanks

the pressure you post for cooler system is common.

The trans gets hot? How hot? Where do you measure the temps?

Ok, thanks.

I do off road racing. Prolonged use will see the temp rise to 250 deg f. The temp probe is in the sump.

It also blows oil out of the breather when hot, which understand can be symptomatic of a worn oil pump. However if the pressure is about right then I guess this is unlikely.
