Hooking up a Trans Cooler Q.

[Ed ke6bnl]

I am using a GM 4L60E (or whatever it is) tranny from my '95 Z28 donor car. The wrecking yard owner tells me that it can sometimes be bad to run a tranny coooler because the fluid can get TOO cool, which is bad for the tranny.

I was thinking about using a radiator with no internal cooler, and the use a seperate tranny cooler, but do I run the risk of the fluid being too cool? I never heard this before.

Is there a guideline for sizing a tranny cooler?

Thanks,

Walt

I put a trans cooler from the shop that my boy works at and I have no cooler in the Griffin rad. this one has a bypass that does not let the fluid go through the cooler till it reaches a temp set point then it will flow into the cooler it is rated for 40,000 gvw
it's a Long Tru-Cool Max model number LPD 4739  13 plates 8.5x22.750x1.250 and good for 40,000 gvw.  

The web site selling this same cooler is http://www.bulkpart.com/cgi-bin/miva?

and they are a good company to do business with I bought the detent cable from them at less then half the going price and fast service. Good luck Ed ke6bnl
