My truck is crapping on it self.......ideas?

Jeff,

Glad you got to the bottom of the problem. I'm interested in the semi-grease you used and if you mixed it with your existing 90wt or used the grease straight?

Veemoney;

I pretty much used it straight. I just drained the 90wt out and pumped the grease in. I am sorry but I don't remember the brand but it was from England. I bought some years ago to use in old Brit Bike Burman transmissions that only had leather seals to keep the lubricant in.

I do remember that it had very high ratings for use in older transmissions and that is why I tried it in the old Dodge.

 

Like I have said it has worked very well in my truck. The transmission had a lot of slop in it and was quite noisy. I assumed at the time that the bearings/sleeves in it were pretty much shot. This stuff quieted it right down. I just figured at the time it was a "Band Aid" type fix and that I would deal with the worn transmission a little ways down the road. I have put more than 30,000 miles on it since so it has easily exceeded my expectations.

Hth, Jeff

Jeff,

I had found this article and a few more on replacing the oil with grease or a grease/oil mix and it is good to hear that it is working well for you on our applications. Thanks for the response.  

Can You Replace Oil with Grease? (machinerylubrication.com)

When I was a kid, my Dad bought the family's first Mopar.  A '49 Plymouth that had a bad engine.  He had one of the local rebuilders install a short block.   Great runnning little car except it had a rear seal leak in the transmission.  He worked for Douglas Aircraft and was getting loads of OT hours.  That was the reason for having the engine installed rather than DIYing it.  So, he decided to put chassis grease in the trans, 'temporarily' until he could get the seal replaced.

 

Never got around to it.  Stayed there until it got traded for a 54 Coronet 'baby hemi' in 56 or so.

 

I wasn't old enough to drive the 49, but he did mention that is was difficult to shift on really cold mornings!

Mine is not hard to shift. You would never know there was this grease in it if I didn't tell you. Not sure if this being a fluid drive makes any difference in this either. I did have a few people tell me it wouldn't work.....but it works despite what they predicted. I figure I had nothing to lose as the transmission sounded like it needed a serious rebuild.
