4T65E Aluminum Transmission Pan

This is our aluminum version of the stock 4T65E transmission pan. It will cool the transmission fluid in a safe way that doesn't require modifying your trans lines or adding a secondary heat exchanger somewhere in your car. Plus this pan comes with a magnetic drain plug so it will catch any metal particles in your fluid and allow you to drain the pan without making a mess like you most likely will with the stock pan.

It comes drilled for the standard 98+ model which uses 6mm pan bolts. Some early model vehicles use a large 8mm bolt to hold the pan to the transmission. We have only seen this on some 97's and earlier vehicles. Please check the bolts in your early model transmission and select '97' if you have the 8mm bolts (standard is 6mm)

Works on all 4T65E HD and non HD transmissions.

Awsome Replacement For Factory Pan

This was super easy to do! My favorite part is the drain plug, and the cooling fins are pretty sweet too. Went in easy with a genuine GM gasket and no leaks. 10/10 would recommend!

Not the best choice.

As usual the fit and build quality of this product is great just like most zzp products. My only complaint with this product is that it does not drop the temperature of your fluid at all my fluid was reading 201 degrees on a gauge and on a infrared gun I put the pan on it the same Drive in the same weather and it read 200 degrees 1 degrees drop is not a drop. For the money buying auxiliary transmission cooler it does look really cool though

trans pan

this is a great pan, it keeps the fluid temp down by 10% on normal driving it dose not get above 200 witch is the Norm 4 my car but the pan keeps it below that Unless I get on it; This is a very good product. If you're thinking about getting it...do it!!!

Awesome trans pan

The pan fit super nice and looks really good. I did replace the drain plug washer with a nylon unit.

It Works!

I recently purchased this for my daughter's "new to me" car. Prior to installation, I have a scan tool which we used live and in real time. Her transmission oil temp. was in the 190s range at cruise long enough to reach equilibrium. One hard acceleration (on purpose to see what would happen) and her fluid was at 212F. AFTER installing this pan (and a ZZP shift kit, along with 8 qts new fluid) for a pan drop fluid & filter change, her trans. fluid at cruise fully warmed is now 167-174F. Got tired of repeated hard accelerations on a deserted stretch of highway to "see" if temps would rise. This pan WORKS and the scan tool proves it. My daughter is NOT a NASCAR driver; she is very gentle and her lowered Transmission temps (along with the shift kit) have the real world possibility of doubling her transmission life.
