4L60e Transmisson Pan

[sumo]

Has anyone replaced their Trans Pan? Im Looking to replace the oem one with a Different one due to a couple reasons. 1 I want one with a drain plug to make less mess when i Do a gasket and filter replacement. 2 I got a supercharger on order so id like to make trans Drain and fills more frequent. Ive been Looking at the PML one that has a drain plug as well as built in Fins to help with cooling and holds a little more Fluid in it. Anyone got Something they tried or recommend?

Do your transmission a favor and put in a very big transmission cooler as well.

Plan to but after the sc install. I don't know how it would mount or how much space I'd have due to the front mounted heat exchanger

Happy with my MagHytec on my 04 Silverado other than installing it was a *****.

My 08 dosnt seem to be bad. Brie exhaust Dosent run under the pan directly

Any other transmission upgrades in the works? I'd imagine that 4l60e aint gonna last forever with that supercharger.

Should be fine. Have a corvette servo installed. Only plan on running 6 pounds of boost.

If your vehicle is not lowered, consider a B&M deeper transmission pan, it will hold 3 1/2 Qts more than stock, all aluminum with cooling fins and drain plug. It will also come with a new longer tube to hold the transmission filter.

Yea I'm lowered 2/3. I went with with the pml

Rather than the pan I'd say spend that scratch on a trans cooler. The tru-cool 40k is thought of very highly and can be had for less than $200

I know that there are guys on performancetrucks.net that have done so with an intercooler.

If I may jump in and ask a related question, my Yukon is currently on my lift with the trans pan off. I am debating whether to do anything with the valve body while it is open. She's at 190k miles. The only minor complaint I have with the transmission is occasional slightly harsh shift from 2 to 3 at light throttle. Its not horrible, but I notice it. I'm tempted to put it back together with fresh fluid and filter to see if that changes anything.

Should I just replace the valve body, or do some rebuild or upgrades while I'm in there?

I have been kicking around a deep sump pan as well, but I tend to agree with the larger cooler route instead.

As for a drain plug, its not a priority for me. I prefer to stick a clean piece of 1/4" or 5/16" tubing down the dipstick hole and siphon fluid out. It is slow (really slow with cold fluid), but I can start the siphon when I get home from work and it will pull a gallon out by morning. This way, you don't even have to get under the vehicle to swap out a gallon of fluid.

Larger cooler route I concur.

(I just replaced a valve body on my 1999 4L60E.) And I believe GM corrected/updated the Valvebody problem they had after 2000+ models. (Heat might still be an issue though.)

I will say though, that I have been through a few different automatic transmissions on a few different GM vehicles. (Powerglide, TH350.) And IMHO GM straight up ****** up the 4L60E.
