hello,

I am preparing to do an oil, trans filter and seal change on my 904 and i just needed to know where can i get the seals for the shift lever, and how to repalce them, as it seems to leak from there.

thanks for the help.

I've bought them at NAPA in the past.
Just about every Mopar with automatic I have bought has had a leaky selector shaft seal.
There is a tool to remove the seal without droping the VB, and I think one to reinstall. I just drop the VB, knock the out one out from the bottom, then pull the new one in with a bolt, nut and washers. The hardest part is pulling the new seal in flush without getting cocked.

Thanks a lot.

I was searching into past posts about adjusting transmission bands, can anybody give me a quick how to, or give me the link of a good procedure.

thanks a lot again

Hello,

already removed the pan and it looks warped, I'll be replacing that. but if i remove the valve body, should i just do the shift kit while in there?

just wondering

thanks for the help

I posted the timken number in the parts list on the main page years ago, it is still there I think. Called selector shaft seal I think.

When I did this seal before, with the valve body out, pry out the old seal. Next get a bolt and nut combo that will allow you to press the seal in from underneath.

I would install the shift kit since you already have the valve body out(while your at it, drain the torque converter, most, not all, 904's have a drain plug on the front of the TC, behind the inspection/dust cover). Installing the shift kit is realtively painless, just make sure you have a clean work surface and keep track of what you are doing. Most kits come with two stages, I did the stage one, and I can't imagine a stage 2 being tolerable as a daily driver. But to each his own.

On that topic,

Anybody tried the mopar performance part # P4007899, it says is the shift improvement kit. or is the B&M kit a lot better?

thanks

I just got that selector seal install/remover tool from E-Bay $10! Sweet!

I used the B and M kit. Have had no problems. Easy install. Many people will tell you that the TransGo kit is the way to go. I have never seen any scientific evidence for this. Never used the Mopar Kit, I wonder who makes it for them? Hmmm...

Anyway, installing a kit will help prolong the life of your transmission bands, and I like the firmer shifts.
