Transmission cooler and oil questions
1. Can you give me a layout of the lines from the transmission to the cooler to the radiator and back to the transmission? I need specifics as far as the top and bottom hookups on the transmission, the cooler, and the radiator. and...
2. I am putting a new motor in- what kind of oil should I use? Should I start out with standard or synthetic and change somwhere along the line? What weight should I use? Shouldnt I change the oil after the first 500? miles?
Thanks,
Karl

I'd use plain old Dyno juce for the break-in...500 or so miles. Then I'd go to syn.

I can tell you that the recommended way to hook one up is to flow it from the tranny, to the radiator, out from the radiator to the cooler, and back to the tranny.
Maybe someone else can give more info as to the flow direction of the trans fittings themselves.

Re: Transmission cooler and oil questions (ill_driver)
I used regular dyno oil for the first 500 miles and went to full synthetic after that time.
As far as the cooling lines go here's a link to the Flex-a-lite website that has the instructions for their coolers. You'll need the Adobe PDF reader to get to this link. http://www.flex-a-lite.com/auto/instructions/cooler.pdf
The front or top line is usually routed to the radiator for cooling, the bottom or back line is the return from the radiator cooler. I installed my cooler so that the fluid first goes through the radiator cooler and then through the external cooler. Other people have said that this isn't the right way to do it as it will over cool the tranny fluid, but Flex-a-lite and the other cooler manufacturer's instructions I have seen suggest through the radiator and then through the cooler and back to the tranny.

No cutting or flaring of any tubes were required.

For the oil in the new engine start out with heavy duty straight 30weight for the first 800 miles and keep the rpms limited to 4000. Then switch to fully synthetic Mobil1 10w-30 and let er rip. Thats my recomendation.
on the tranny line plumbing; out of the tranny to the bottom of the rad out the top of the rad thru the cooler back to the tranny. Ide recomend synth tranny fluid as well.
