4L60E Transmission pan

I am being told that the 4L60E Automatic Transmission was equipped with two different oil pans, a shallow version and a deep version.

Can anyone tell me what the differences are so that I might determine which one I have?

This knowledge will help me choose the correct filter.

Second question. I am looking to get the most mileage out of this 1999 Silverado with the 4.3 liter V6.

Will moving to an aftermarket, cast aluminum, finned transmission pan be a worthwhile investment? Approximately $100.

Thanks!

Sorry, dont know which is which.

I think the easiest way is to call the dealer and ask them.

I think its better for you to install a transmission fluid cooler, that would cool the tranny fluid much better than just a finned pan.

One pan is 65 mm deep, the other is 70-something deep.
I bought both kits at my dealer and took back the one I did not use. They said it was ok to do. Luckily I had the short pan, $27 and change for kit, deep pan was $40. I bouth a little hand oil pump years ago at Wallmart. I slide a hose down dipstick tube and pump out as much as I can. Makes for a lot less messy change! :licka:

Hmm, so yours didnt come with a drain plug?
I wonder if thats just only with V6's

Mine is a 98 with that transmission. No drain... no pain!
