Default rebuilding a 5speed

so I have a the original 5 speed tranny from my truck that has just been sitting at my work place for about like a year. Anyway I was wondering if its hard to rebuild one my self? Is there a rebuild kit? I don't care if its a waste of money I wanna do it as a learning experience. The reason I had to put another tranny is because that original ran out of oil and it stop turning the drive shaft. It will turn if I get plyers and turn real hard but wont spin freely how they are soppose to. Any advice or comments are wanted. THanks guys.

ive rebuilt a few 5 speeds, its not overly hard but with some transmissions you need special tools. there should be rebuild kits floating around, usually theres some on Ebay

if it ran out of oil, i dont know how saveable the trans is. rebuild kits you usually get synchros, bearings, and seals. i dropped the 5spd trans on a SUV that ran without oil, a gear blew up and there was metal shavings EVERYWHERE. if something like that happened on yours, i wouldnt even rebuild it

well I have a Haynes repair manual that shows the transmission's exploded view. So Ima take it apart just to get familiar with it and just to learn how it works. ill take pics to show you guys how bad it looks.

use the FSM, it will have a step by step. you could check with Napa and the like to see if there is a synchro set. best way to do it is have a large clean area to lay stuff in a row as it comes apart.

Factory Service Manual. Trust me, you will want this.

To do the Hardbody transmission, you will want a hydraulic press. There is also a special service tool to torque the nut at the end of one of the internal shafts. I made one, based off the measurements in the FSM on it, out of some 1/4" x 2" flat bar. I also made one out of a socket sliced in half and "lengthened" with a section of pipe. Same difference, but the FSM-style one was easier to use.

It's not ~hard~ work, but it is lengthy and involved.

I intended to do a write-up on my rebuild, but the FSM does such a good job, I had nothing to improve on - and stopping to take pictures of everything was slowing me down.

I picked up a rebuild kit through my local Transmission shop. http://www.drivetrain.com/ is another source - same kit. Reasonable quality. My kit was $260 Canadian or so. My transmission had a two-piece synchro ring, and no reverse synchro.

Tranny went in earlier this year, and I've been running it in Redline MTL. Or maybe MT90. I don't remember.

pick your year out. if its earlier than the 1989 then use that one. 1990 covers to 93.

the rebuild kit is probably 200 bucks, give or take a few dollars. if it ran out of oil, im sure it cooked everything in there.

Yeah most likely it did fry everything but I'm curious to see what it looks like inside. I'll probably just recycle it for metal or aluminum.

Do it, just get some tools. Id say snap ( internal and external) pliers. Would need someway to press bearsing on and off.

Im thinking if doing something similar but rebuilding a engine. Id like to learn and see everything inside. I just need a donor. Your in luck you have a donor.
