Tranny cooler and tranny crossmember ?'s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Yukon Jack** · 08-04-2003, 04:07 PM

A buddy is putting a TH400 into a truck with a 283. The radiator is not set up to act as a tranny cooler also. Should he be okay if he just gets an external tranny cooler (passive, without electric fan) or would he be better off getting a new radiator with built in tranny cooler? The radiator he has is in good shape so it doens't need to be replaced.

Second question, he is trying to remove the tranny crossmember from a 1972 pickup and he is having difficulty getting the crossmember out of the frame. Does he need to break all of the rivets to get it out?

ok first off yes the external cooler will be much better than using the one that would be in a radaitor. secondly is the crossmemeber moving or no? if it moves you have to push the passenger as far back as it will go and pull the driver forward it comes out on an angle

Only the rivits that are attached to the fram need to be removed. I had to use a deadblow hammer to get mine out due to the rust build up.

external oilcoolers cool much better than the combo with the radiator the down side is during the cold of winter the combo with the radiator warms the tranny fluid to correct operating temp much better
