I got my gears done about two months ago a month later I took it in because there was a slow drip at the bottom and the put a fresh seal and new oil in there now it is doing the same thing. Did they put a chitty seal or is it because I have the shift pressure turned up to high? I really like my shift pressure being high. Any help is good.

 

I have a VERY small pinion seal leak.. I ain't worried about it yet. It doesn't drip..

 

It's a know problem with out rear end housings. But you are the first post I have seen when there is a problem after a gear install. The seals are bad for the start so during a gear change they are replaced (should be) which generally eliminates the problem..

 

I had one after a gear install. A fairly fast drip actually. Had in to be re-sealed 4 times. finally took it to the dealer and they used a sander/grinder and buffed the housing down and made a better seal. So far, so good

 

My differencial has dark oil sepage marks on both sides of the rear seals.
Not close to a drip or anything.
Does anyone think this is a problem that I should have the service dept. look at before my warranty is up in 2 months

 

if i took this into my service department they would just laugh at me. since they are aftermarket gears. i think i am going to just keep an eye on and change the diff. cover little later down the line make sure the seal is clean myself and put royal purple in.

 

Get it done at the dealer asap. I had that problem and slowly it effect my parking brake to the point where it was not gripping the rotors and not to mention messy rear brake dust cover and wheels. It took half day for dealer (uner warranty) and been fine since (20000 miles later). I think my problem started when I took my rig in to get new clutch pack and they had to remove most of the rear end and most likely didnt do a good job of putting things back together...anyways it is all good now.

 

they are probably going to charge me since i didn't get the gears done there though.

 

Does increasing your shift pressure cause added wear on your rear end or transmission?

 

Both. In seperate ways.

 

Well i do believe i will be turning my shift pressure back down to zero on my edge. I like good performance but i NEED extended life from this truck.

 

Slipping, smooth shifts, is one of the causes of wear on a transmission.

I'd turn it up a little bit, just not too much.

 

They prolly bent the cover a little when removing it to drain the gear oil. I would take it apart. Clean both surfaces realy good til they shine. Throw some blue rtv gasket maker on there and give it about 15 minutes to setup and then reinstall the cover and torque to factory spec. Add fluid and hopefully no more leaks.

 

How does added transmission shift pressure affect the rear end? They don't share fluid or anything like that.

 

Took mine in to have 'em change rear diff fluid and put on my Mag-Hytec diff cover--same thing. Covered under warranty. I have changed gears to 4.56 amd have a s/c that was running with boosted line pressure for firm shifts. Hope this won't be an ongiong problem.
