The rebuild manual is on its way, and I'm going to go through the process and get together the assemblage of everything I need before I start, lock ring pliers, pipes to dislodge seals, etc. It's been sloppin gear oil around pretty profusely, so it needs cleaned.
So here I ask, any sage advice before I get started? There's lots of rebuild kits, and I've been looking especially close at D&L's. Anyone have another kit suggestion? Any tips from past experience?

I used this company to order manual transmission parts for a '62 3sp+od. With the economy the way it is a call to the several companies you can search on ebay will allow you to obtain the lowest price, all-american bearings, more complete kit, etc. A parts washer would be handy, rebuild manual, tools on hand. I don't know what you mean by, "It's been sloppin gear oil around pretty profusely, so it needs cleaned." That's what happens inside of these old trannies, 90 wt. gets slung around. Do you really need a rebuild? Have you changed out the 90 wt.? I'm using 90 wt. synthetic. Here's another thought. Daily driver = Rebuild The Transmission. Parade or Seasonal Driver ~ several hundred miles a year = New 90 wt. synthetic and spend yer money on wax.

Yeah, that thing about cleaning it, that was just sort of an errant thought I typed out for some reason. Actually I think the seals at either end are probably shot, so the whole outside of the thing is a mess. I've been adding gear oil regularly to keep it happy.
The truck is my daily driver and chief means of travel, so I'm trying to get as prepared for this as possible, pull the thing on a Friday and hopefully having it back in before work Monday. If I get in there and things are a real mess, like I want to replace a gear or something, I can always ride the bus for a while.
I don't have a parts washer, so I'm figuring on getting a buddy to take me down to the carwash with the main case and extension and clean those up that way. | | | | | Joined: Oct 2005 Posts: 83 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2005 Posts: 83 | Job completed successfully, fairly straightforward stuff.
