Transmission Rebuild Thread

[vex]

Could we please have one? I'm about 1-2 years out from rebuilding mine (FC NA) and I would like to see individuals who have rebuilt theirs and what they did as well as prices if possible.

I would have rebuilt mine back in 05 and possibly done a write-up, if I had the forever-long puller arms to get the gears off haha. I keep forgetting to look for the proper tools to do it. I'll do a write-up if I can remember...or if I can even remember to do the rebuild haha.

I made forever long arms for my gear puller when I rebuilt my tranny .I have used them on several other rebuilds. Use good material and they will last and do the job .Use strap metal and waste your time .

[speedjunkie]

^You had to make them yourself? I don't have those skills...only bow staff skills, nunchuck skills, drawing skills...

Care to make another set and sell them to me? lol

A largeish press and bearing pullers would do the job as well. The write up is already out there, it's in the FSM ;)

the two trans tools mazda has are the giant long puller set and the giant socket. i think the socket is 36mm, but its a couple feet long so you can put it over the shaft and loosen the nut.

the socket also doubles as the bearing installer, although a few feet of 3" pipe and a couple old stationary gears work really well here too. the bearings are not a very tight press fit.

This thread was made just in time, since I damaged my 4th transmission. I have no more TII trannys left so a rebuild is in order. So far I have two of my old trannys apart. The S5 TII I just pulled from the car has a damaged 5th and reverse clutch, and the previous transmission I had in the car (S4 TII) has both synchros on the 5th and reverse clutch broke in half!

I just made my gear/bearing puller from some steel stock I purchased from Lowes, now I'm working on a way to remove the nut on the output shaft (rather than using a chisel like I did when I removed it).

i think the socket is 36mm, but its a couple feet long so you can put it over the shaft and loosen the nut.
That may be true but I swear I measured 40 or 41mm, I'll have to double check. I was thinking of using a crowfoot wrench and extension to remove this nut (if it'll fit in there, will check later). like this:

the socket also doubles as the bearing installer, although a few feet of 3" pipe and a couple old stationary gears work really well here too. the bearings are not a very tight press fit.
After reading this I'm thinking of ditching the crowfoot wrench idea and just buy a socket, chop it in half and weld it to a pipe. Better idea since it doubles as an installer as well.

I went to Mazda when I got off work yesterday morning and picked the guys brain on the parts I needed. Apparently all Mazda dealerships worldwide are liked together and when he looked up the 5th and reverse clutch, he said there were only 7 left! Hell, i need 2! so when they're out, they are out! There must be a cross somewhere to another manufacturer because if I need a pair for two different transmissions then its gotta be a common issue. He even said that it may not be available even though the system displayed 7 available, so I'm crossing my fingers :(

I'll take pics of the gear/bearing puller I made along with pictures of the nut socket/bearing press I'm about to make.

[FC Zach]

Here's the pics of the bearing/gear puller I made from steel stock I purchased from Lowes:

The 41mm socket in this pic was given to my neighbor, he works in a machine shop. When I get the socket back it'll be capable of removing the nut and reinstalling the bearing. I'll show a pic of it when I get it back, should be sometime this week.

good shit buddy.....now i no how to make my own when the time comes.....:biggthumpup:

[speedjunkie]

Nice! I never even thought of using the steel from Lowes. I could have done this a long time ago lol. Good idea on the socket too, I may have to do that as well.

[FC Zach]

I got my socket back and have already tried it out. Works well and did exactly what I needed it to do, cant complain.

ford also uses the installer kit on their older cars, its how i did the 5th gear syncros on my fd trans

so if anyones friends with a ford tech, ask them to dig up the old service tool out the back room lol

[Raksj04]

I know the one of the major chain auto part stores sells a rebuild kit with syncros for about $500. I forgot which one. it was for a S4 turbo trans
