Trans Cooler I am having a hard time finding a Transmission Cooler kit. I have a 2001 Trans Am Auto. Putting in a 3600 Yank Stall. Just got back from overseas and I am learning my car. Any help/link would be appreciated!

Go with the B&M 70274 super cooler. 29,400BTU of cooling power. Super common on the forum.
sold on multiple sites , this is just a link so u can see it.

See below:
A few short notes to add:
1. The B&M oil cooler... while operating quite well, is a over-priced re-branded product.
It currently sells for aprox. $130 through Summit, Jegs, and others...
For example:
Summit sale link
The same product can be purchased as "Long Mfg. LPD4711" or "True-Cool M7B".
Pricing is usually $70 - $80. Do not pay more than this...
For example:
Amazon sale link
2. Those of our cars and vehicles that are older and did not have OEM 3/8" diameter transmission oil-cooler lines installed...
Really should have the smaller 5/16" lines upgraded to 3/8" hard-line or -6AN hose.
This simple upgrade/ change actually had a great beneficial impact on the transmission oil cooler circuits and torque-converter charge circuits.
Life expectancy is increased from just the increase in cooler-line size (flow and temps here are improved).
GM made the change to larger transmission cooler-lines across the entire portfolio of vehicles... this is how beneficial the effect was!
3. Be carefull with any "Summit" or "Jegs" branded fittings/ hose-ends for AN lines.
They are generally perfectly fine for "One-Time" use. Meaning installed and never removed or altered.
These tend to strip the threads/ become damaged once taken apart for reuse.
If you plan on ever servicing/ disassembly of the AN lines; spend the money for a name-brand product such as "Earl's".

Get yourself a nice Derale remote cooler with built in fan. Your transmission will thank you

I went this route...Mishimoto Heavy-Duty Transmission Cooler with Electric Fan | Mishimoto
NEVER heard of over cooling a transmission (I guess "could" happen in Antarctica ?)

There is essentially no harm in over-cooling unless taken to an extreme...
Where condensation could be chilled and then re-warmed to have unwanted water enter the ATF...
Not that it properly mixes/ combines.
However water is very bad for all the Materials and Components of the Transmission assembly.
Some of you may have recovered Transmission Assemblies that have taken on Water in some way or another...
It's a very bad time!
Regardless of all of that...
There is actually a Temperature Window where the Transmission Performance is ideal.
So if that is important to you, or some sort of Elapse-Time is a Goal of yours...
ATF Temperature is actually an Important factor; and TOO COLD is NOT GOOD.
Realistically...
Remain in the 160 *F through 180 *F Temperature Range for optimal Performance!
Track and Laboratory Tested an absurd amount of times!
