First let me say thanks for all the help this site has been. I got a 2001 2500 4x4 auto SWB last Saturday. It is all stock and has 68k on it. Here are my questions.

1. I have a deep pan on the way and would like to know what ATF , if any, is better than the OEM stuff?

2. Is there anybody that sells the vacuum pump seal kit online? It has a leak there and I found the part number for the kit on here, it said Geno's sell them but I could not find it on there site. I called my local Cummins dealer but they did not have it.

I really like this truck, but I need to get this leak fixed so that I can enjoy my truck.

 

Use the ATF+4. Plenty of people use Amsoil as well.
Call Geno's. They have a LOT of stuff that is not on their website.

 

Marine is right...

But the ATF+4 is a dealer item.

 

get penns syn blend ATF its suppose to be dang near same as amsoil but half the price

 

Will they order it for you?

 

Yeah they will but if I can get it from a board vendor the I would rather do that. I am going to call Geno's tomorrow.
