New larger Hayden Performance Transmission Oil cooler, with enough Valvoline Synthetic oil to top off tranny fluid, Mobil One Extended Performance 10W30 Synthetic oil with a over-sized NAPA Gold oil filter (1995 Chevy Blazer 4.3L filter to be exact).

Transmission cooler installed, engine/transmission warmed up for tranny fluid filling and engine oil draining.

Here are a couple pics.
I cut the original upper trans cooler line close to the cooler so less rubber can go bad, and ran the new rubber around the radiator to the end of the lower line that comes from the transmission. Already had the rubber in the middle of the to lines to trans replaced so my transmission, lines and cooler are all fresh.

Tranny cooler install is only a 1 beer job. 2 beers and you are working WAY to slow. :P

Nice choice on the motor oil and over sized NAPA Gold filter.... very good quality

hmm must have been a fluid changing weekend in MN. you lakevilleSSEI and myself changed fluids.... only you had some add ons!

Did you bypass the radiator? Srry if thats a dumb ?

No. Should I have? It'd be no real problem.... just a 2' piece of hose would be all I need.

any idea on how many degrees colder it will run with that? or is it mainly so the trans does not overheat in the city?

Well, from what I know from Bill W, all the rad core does is help pre-heat the fluid. It doesn't do much in the way of cooling.
He bypassed his with a large rad cooler. I'm not sure if yours is large enough?

Yes, bypass the radiator completly. Not only does it help warm the fluid you're trying to air-cool, but if the radiator does develop a leak between the transmission cooler and the inside of the radiator, you'll start running coolant through your tramission and vice versa. An unlikely occurance, but one that has happened to me in my 91 Lumina and caused the failure of my transmission.

Well hell, we all should just met up somewhere and done this all together here? Hahaha

Tranny coolers next on my list.....I'm looking for something that has fans on it though....so in traffic I can still get the air flow....

Seeing how I live in the cities....Traffic'* a *****.
