Can I block PG cooler line fittings?
 

What happens if I just block the oil circulation from the cooler? Does something break or what? My tranny guy told me that powerglide is designed so that if cooler gets filled with trash, particles etc, the tranny still works.

Original tranny case and I think it's original pump.

You circulate from the trans into the cooler and then out to the trans so, the only place the cooler can pick up any debris is thru the fluid coming into it. If you got debris that is going to create circulation problems in the cooler, you have bigger problems in the trans. If you eliminate the trans cooler, your trans temps are going to get ridiculous and your trans is not going to like that either.

maybe he meant he blocked the cooler bypass off ??

No, I meant just what I wroted on the first post. I didn't have cooler in my PG with last 150 passes, changed oil every 50 passes and it seemed to be ok. Tranny temp never got over 180F.

I have just line that goes out and then back in the case and that line has leak so I thought maybe I could just block the cooler line fittings completely.

It has to still be looped for the fluid to move if not you'll have major issues.

I got to ask why would you not want to run a cooler? Is this a car that is towed to the line with very little run time to build any type of heat? You would still want a loop for circulation purposes but that is just my opinion.

X3 you've got to loop them.

To me, looping the transmission "COOLING" lines would be the equivilent of looping the radiator hoses, it's never a good idea to take the cooler part of the equation, wheter you "THINK" you need it or not.

If your tranny is only running 180 degrees then think how cool it would be if you did have a cooler? You might not even have to change the fluid then? It for sure would last longer, it only takes a small cooler to do alot of work and IMO installing one would be, by far, one of your better investments.



JM> 2 cents, Cp

Its your decision whether or not to run a cooler, but the cooler you can keep that glide, the better. DO NOT plug the inlet and outlet. You must run a loop or you're headed for problems.

What kind of problems?
