my mechanic tells me that overfilling the Getrag by 1 quart + is stressing the front seal and may result in clutch slippage...thoughts?

 

Sounds like BS to me.

 

Lol

 

Even if he were correct a front seal and a clutch is far cheaper to fix than a Getrag that is locked up. If he wants to discuss it, we can sit around my locked up Getrag and have some coffee Mark

 

Park your truck w/ passengers side up on a 8"curb. Take the plug out, should take an extra quart no prob.

 

i ran my old truck for a few years with 5 qts of amsoil 75-90 and i never had anything leak.....and when i overfilled mine i took my whole shifter off and just poured it down the neck of the trany....i'm fixing to do that with my new truck next week

 

fyi ....there is no mech out there that knows more about our trucks then all these wonderful guys on the dtr......just remember that

 

Keeping a seal completely submerged in oil when it was only designed to be splashed by the oil is definitely harder on it, and is asking more of it than it was meant to do. Certainly there are hundreds of people who have done it with no problems, the same way there are hundreds of these trucks that have never had a KDP problem. You are merely increasing the risk of a seal failure. Whether you deem it an acceptable risk is up to you.

Personally, I'm quite willing to throw a bit of extra oil into a Getrag, while on my differentials I tend to keep the level slightly below the fill plug to make life easier on the seals.

 

its been my experience that most mechanics dont even know what a Getrag is.

 

Yes we do, its the rear end in the corvette's....LOL

 

X2, they make lots of gear boxes for lots of different types of cars...Mark

 

I think It is a unofficial TSB. I know I heard of it right from a Old Dodge Mech even before I had the Getrags .

 

if there is a sticky on this site, I will print it and show it to my mech

you guyz do know more about our trucks than a general mechanic

 

just bought a rebuilt G360 from Jim Clark (was "jjeeper" on E-Bay, now uses "Tristate Transmissions" as his user name). For those of you who don't know him, he's a nice guy in his early 60s who rebuilds trannies for a living. Very pleasant to talk to and he ships Getrags all over the world.

Jim ships all of his G360s with five quarts of Mobil 1 5W30, which is available at Walmart for about $22/gallon.

He told me that the seals are NOT stressed by the extra oil, that there's a breather just forward of the shift assembly that relieves excess pressure

 

He is right, this transmission uses the gears to lubricate itself. There is no oil pressure or sending unit in the 360. The seal is metal coated with viton. The newer kits use a better compound. I wouldn't worry about it, no way it's going to leak unless your shaft is a bit loose
