Sonnax Line-to-Lube Press Reg valve 80E
 

Does anyone have any experience with this valve? It supposedly increases cooler flow under Low RPM conditions.

My trans temp rises quickly and unless i take it easy, it seems like it wants to just keep going up. I have a Tru-Cool 40K mounted behind my bumper with a small fan that covers about half of it. I was wondering if this valve would help at all.

No experience with the kit, however the fan mounted to the Tru-Cool is killing the cooling performance. Only 30% of the area covered by the fan (the outer edges) is seeing any real air flow and the other 60% is probably not getting anything. Only good way to make a fan work with a tru-cool is to build a shroud and pull air through.

Also, my 80E will pump 3 pints of fluid every 10 seconds at idle, so I don't know if boosting the flow will help you much.

I put one in mine when i rebuilt it. What would you like to know?

Mine has one, but I never ran a stock 80e to compare to.

Mine pumps 3 pints in 10 seconds too. That's how much pissed out on the floor when I started it with the pressure plug out after the rebuild.

What temps do you see, where is your cooler mounted, and did you bypass the rad?

I know your trans runs around 145, but where do you have your cooler mounted?

I'm going to take suburbazine's advice and build a shroud for my fan. It's something i've been trying to avoid, but it needs to be done.

Mine mounts in the front grill behind my heat exchanger.

Mine runs 145 tops. I have bypassed the radiator and it is mounted behind the grill infront of the ac condensor thing.

The only space i have behind the grill to mount mine, would be sandwiched in between the condenser and radiator.

Should I try that? It would be easier than fabbing up a shroud...

That's guaranteed airflow so that would work. Might not get as cold as being in front but it would cool better than at the moment.
