You are entirely correct.

You are completly incorrect dude. No Third Gen ever had an electronically shifted 700R4. (a 4L60E) They all have TV cables and no extra computer for the trans. As a matter of fact even the 1st year 93 4th Gen had a 700R4 and the 94's-on used the 4L60E instead.

AGH! He is NOT incorrect, 4L60 and 4L60E are 2 seperate transmissions. 4L60 is the SAME as a 700R4, a 4L60E... see that E on the end? Thats the electronic 4L60/700R4 - example - a 1991 Corvette came with a 4L60 - a 1996 Corvette came with a 4L60E.

**** **** **** ****, I can't believe I confused that. Well at least my info was correct, if that was what we happened to be discussing. And yes in the later years all they did was change the name with no differences.

Some people use the radiator's internal transmission cooler and add a seperate cooler just to help the radiator out - but by completely bypassing the radiator, you're removing all the transmission heat from the engine coolant so reducing both transmission and coolan temps - n face it, in a 3rd gen, the coolant can stand to lose around 40 degrees
NONONONONONONO never unhook the Tranny from the radiator....you will only HURT tranny cooling this way....use both a external cooler and the radiator and a deep pan is a great idea....the more fluid you have in the system the better, and it's harder to burn it this way....the aluminum tranny pans with cooling fins are also a great idea because they do double duty....I would still use a tranny cooler first though

Umm....if you use a decent size fluid-to-air cooler then it's much more effective than the "fluid-to-200* engine coolant" factory setup. The factory rig has much less cooling capacity because the cooling medium itself is very hot. It's like working out and then trying to cool off by showering in boiling water.

You do have to use a good-size fuild-to-air cooler though, or it won't cool the fluid enough due to lack of surface area.

Ok I'll agree that if it has enough surface area then that's true....but if the fluid goes through the radiator and cools some....THEN goes through the aux. cooler after it's at the lower temp from the Radiator, then the Aux cooler can cool it even more....instead of just getting the cooling capability of the Aux. cooler you get both....but if the fluid goes through the cooler then the radiator you're working against yourself
