Turbo 350 or 400 trans cooler lines

Is a cooler necessary in a glide bracket car?

I would, especially valuable in the later rounds to protect trans.

Most in stock and Super stock don't use them is they are not effective. The cooler is used for such a short time during the run. The cooler only works when the engine is running and you have fluid circulating through the cooler and air running over the finned surface. Most run a deep pan with larger volume of oil. I have a powerglide and have never used a cooler. Never an issue with the trans from temp related issues. A few years ago we had a double race at an IHRA open. I won the first race and went to the final in the second race plus a couple of qualifying passes. No issues with the trans that day. The car was dead on consistent all day.

I could never fully fathom the theory of a deep pan myself. Just a larger volume of fluid that once hot, remains hot...probably takes a tad longer to get hot is all.

The reason for a factory deep pan is to provide a greater volume for the oil to expand in to . The factory dipstick is re-calibrated so the fill volume is the same . This is done mostly for trucks, where the trans temperature runs hotter . If you put a deep pan on the trans, and use a dipstick for a shallow pan , you will have extra oil in the trans and when it gets hot , it will expand up into the rotating parts . This will cause the oil to get whipped up into what will almost look like a milkshake , and cause all kinds of problems , like oil to come out the breather . If you run a deeper pan it there to get the oil away from the rotating parts .

I run mine where I can just see the fluid on the tip of the stick. I also have a finned pan that helps radiate some of the heat away. On a hot day you can put a fan to blow air under the car and across the fins to help a bit with cooling.

Maybe I'm just hard headed, but most of that just doesnt make sense to me. Regardless of how much fluid you carry it will eventually get hot...a few extra quarts would just extend that time a bit. As far as keeping the level away from rotating parts...what parts? Half of the fluid is held in circuits anyway. I would love someone to explain exactly why there is a benefit to running a deeper transmission pan.

Thus far the only logical reason for a deeper pan I have heard to date is to keep the filter submerged during hard accelleration...not sure how big a problem that is with factory depth pans.

Another oddity...here is a TCI pan that doesnt even allow a longer filter/spacers -
