Re: ax 15 synchros shot.. need advice

OK, You don't buy a "kit", you take it apart, inspect it, and replace what is needed. Usually, you can pretty much guess what is wrong with it by driving it. Normally only 2nd and 3rd brass is needed. The dealer sells all parts seperatly. I think the brass is something like $20 ea. It is a good idea to also purchase the input seal. There are no gaskets, you just use Mopar RTV.

1. Ok, if no one else will take a shot at this... I will.
2. I've rebuilt about 12 manual and automatics over the years outta desperation.
3. Each time it gets easier.
4. You can get the parts kits On-line.
5. But for these parts I go to the local transmission rebuilders and ask
6. "Where do you get your parts?"
7. Because they shop for quality and price.
8. They don't want customers coming back for a blown seal from a cheap kit.
9. They usually buy quality.
10. So, I talk to them to get a consensus as to where they get their parts.
11. First place to investigate is a NAPA rebuild kit... they're tops in my book.
12. But I don't know if NAPA carries one for your transmission.
13. Then I'd go other aftermarket vendors.
14. Then, and only after all avenues are exhausted would I order parts from the dealer. [img]images/graemlins/mad.gif[/img]

Um, you sure your clutch isn't worn out? It sounds more like that than needing a tranny rebuild.

Re: ax 15 synchros shot.. need advice

the clutch is fairly recent. there is no slippage or chatter, and there is no drag. engages and disengages where it should. red line trans juice helped some, but not entirely. doesnt do it all the time. i've got a friend that used to work on british vehicles, and he also is pretty sure its the synchros. he has a machine shop and builds small operational trains that you can ride on from mostly raw stock. i trust his knowledge of transmissions and gears....
