Ok since the cheap o pos I had on the car took a crap and cost me a run Thursday. What are you guys using for the transmission cooler? I know Derale is kind of standard , but figure other choices to look at too.

With the ability to run high gear only I figure will need an efficient one as well as not leaking. I have two of the old AC coils we used way back, but sure far from efficient and way of weight-wise.

Other than Derale which is a very possible option. What do you have or just never had other than Derale? Oh yea what size cooler?

Limited to about 10" tall due to mounted under seat in the rear of car. Above transmission as would like not best. Puts it in the ****pit with me and that means more heat.

IMO, use a stacked plate & fin cooler. They're durable/efficient & use the biggest one you can. Pick the manufacturer of your choice.

Here's an example:

The funny thing is that looks just about like old AC coils we used 30 years ago and have been told not to use for a few various reasons.

Guess I could clean out out check flow and hook up run transmission with TB and check temps entering and leaving,

I had 2 B&M coolers spring a leak in 1 season, the B&Ms were back ordered so I put a Derale in and never had a problem after, and trans ran cooler too.
The Derale also has a higher pressure rating, I am pretty much sold on them

I just came in from putting one of those on my truck....Last weekend in Vegas was the first time the trans has ever got up to 200* towing....funny thing though it would creep up to 180* just sitting in the pits idling with the a/c on.....I love my old workhorse but I would have melted it before I got out of that nice 75* air in the cab....That was a 108* weekend that felt like 120*....hell it might have been 120* with the firesuit on...lol

Both of my Altereds have Deraile coolers. One has a thermostat like this to divert most of fluid back into transmission until temperature is up over 160* and then it starts running it all through cooler. I also use a thermostat on the fan that kicks it on when it gets hot.

Cheap coolers will break and leak and that could even cause a crash in addition to really messing up a track.

Some coolers do not do much cooling anyway.

Just get a good one one time and one other thing on transmission lines I only use the PTFE lined hoses. I have seen some other steel braided lines get soggy or soft with transmission fluid.
I do not take a chance on that any more.

Like I said in another post as a bracket racer you set up the car so you can do most everything possible yourself and do not need crew. My transmission cooling system I do not need to put a blower on it to cool it or ever really worry about transmission temps any more.

PTFE lines do break also. Not even transmission fluid but oil. Ask how I and Peidmont Dragway know. I have heard 8 qt's of VR1 50 w is bytch to get cleaned up.

I have my pit cooler systems about done. Just need cooler to keep temps manageable and consistent. If pit cooler works as designed it should drop temp pretty quick with simple two connections and flip of switch. I will have one for both transmission and oil. Using car cooler and auxiliary cooler with system pumping through the transmission also. Should make fopr quick cool down.

Oil cooler side will pull from pan through cooler back to engine under intake. Flodding lifters and draining back pulling heat out as it flows back to pan. The bonus is I can change the oil w/o jacking up car or getting on the ground and that's huge for an old guy.LOL

Looking to see what is the biggest cooler I can fit between the seat and frame.

Derale seems to be the go to for car ooler.

^^^This. Although on my digger I run a Shogun KoolKan, but changing that one out for a B&M version of one. Never have an issue with fluid temps even when hot lapping and no wires to hook up...Kool Kan will be for sale if anyone is interested
