Where do you buy transmission parts?

[JET]

::shakes head::
contact shep racing, he purchases directly from TRE.
Are you sure about that? Shep doesn't like TRE much and when I got my tranny done, the parts did NOT come from TRE. He had them custom made.

it'll be more expensive though after you fuck it up and end up sending it to someone that knows what they're doing :)

This guy is right :)

I know that, but I'm going to have/want to learn to do it myself someday. I'm not 100% sure if I'm going to do it myself yet...I dont feel like screwing up either. We'll see what I end up doing.

Seriously, rebuilding transmissions is hardly rocket science. True, there is a chance you could muck it up if you have improper tools and are not paying attention to detail (or just randomly decide to pour gravel into the tranny for grins...)
Anyhoo, here are a couple of good tutorials:

tut01 (http://www.twingles.com/ideck/rebuild3/dretranny.htm)
tut02 (http://www.geocities.com/htamotorsports/rebuild.html)

Ultimately it comes down to price. Lets look what you get in a standard Shepherd rebuild:

New 1-2 fork
New 3-4 fork
New Shepracing spec 2nd gear
New 1-2 hub/sleeve kit with double synchro rings
New 3-4 synchro rings
New 5th gear synchro rings
New 1-2-3-4 synchro springs
New input ,output ,and both drive shaft seals
New Input shaft bearings
New intermediate gear bearings
New roll pins
New end nuts
New center diff side shims
New nylon shifter pad
Shims for setting preload

The only thing that jumps out at me is the spec 2nd gear. The rest of the stuff can be bought relatively easy.

I haven't rebuilt a transmission in over a year (only reason I have to open this one up is because some clownshoe broke the rail end on the 3/4 rail by ripping on the shifter...) so I cannot get current prices for you. The prices do vary quite a bit depending on where you go. For example, I was quoted $75 for the front input shaft bearing by Mitsubishi. So, just for fun I called up the Eagle dealership (both are owned by the same person in Duluth) and was quoted $27 for the part. The only difference was they had different CAP numbers. In addition, I am able to get some of the bearings from a NSK wholesaler as well but for some odd reason NSK now have different part numbers then what is stamped on the original transmission bearings.


When I get time, I am going to send John an email (and beg TRE) and also get a current price listing for some of the stock parts form Mitsubishi. I'll report back in when I have more information.

Thanks...that would help alot.

You can only learn by doing. I never thought I would ever be pulling motors out of cars and I have done several last year. I may experiment myself on the tranny rebuild if I ever get time this summer. Cannot be as difficult as everyone thinks. Pull apart with correct tools (have plenty of gear pullers, etc at work) inspect for worn parts, and put back together in order. Then make sure dowel pins are in and throw on the tranny.

I honestly would probly never send a tranny to Shep or TRE. They are expensive as hell. Rick Shindley has done several and charges in the $200-$250 range plus parts of course. Learning the skill to rebuild a tranny is priceless in a dsm. Who hasn't gone through a synchro???

I tried rebuilding mine. I didnt have the correct gear pullers and a few other tools. Thats is why I quite and gave it to mitsu. I just dont know why everyone thinnks they can do this kind of work when they have no experience. Sure you can do it with no experience, just dont get mad when you mess it up a couple times and you have to rip it out of your car 2 or 3 times because you made a error here and there and it wont shift. Tranny's are pretty complicated and if your a first timer with no tools at all then Id say its not a good decision.

To me, someone with not alot of extra time to mess with a tranny, I would be better off letting someone else deal with it. Unless I really tackled it and got all the right tools to pull bearings and gears.

The tranny is probably the hardest thing I have done in a DSM. Rebuilding the engine is way easier. I did eventually get mine to work, but that was the last one I will do. Shep now gets all of my trannies. He knows the exact gaps and does special tricks to get them to work better. This is one place I would not skimp on. Spend the extra $350 and have Shep do it.

If anyone is interested or know of a trusted well-known member of the community that would be interested in rebuilding a 91 MR2 tranny please let me know, =].

There is quite a difference in price versus Shindley and Shep. Not only $350. We are talking about costs of ~$250 (for Shindley) and you can drive it over to him. Shep is $900 for labor and you have to deal with shipping. That is a signifigant difference in my opinion. You could tear through a couple of Shindly trannies before justifying the costs of a Shep tranny. I can imaging that it takes Shep a lot longer to fix your tranny and send it back to you. Shindley can do it usually within the week. I have heard nothing but good from Shindley rebuilt trannies.
