Having trouble getting into 5th gear. and as of right now its pretty much locked and i cannot shift into 5th. ive been trying to search for the solution but ive been reading more and more that the brass synchros in the ap1 can wear out and even "burr". just curious if id be able to swap for the carbon ap2 synchros..

 

Doubt its your synchros. Try changing your transmission fluid (I suggest synchromesh) and doing this:

Solved my problem. You'll be no worse off if it doesn't work. Definitely worth a shot before you drop all the money on a rebuild.

 

AP1 service parts are carbon coated.

 

Even if they do it is probably cheaper to buy a used tranny.

+1 for Synchromesh and the gear change while parked

 

Buying a used Ap2 tranny will be significantly cheaper than trying to retrofit the AP2 synchros, IIRC you have to replace nearly all of the gear sets as well and they are insanely expensive that way.

 

changed the fluid today no metal shavings or pieces came out... even stuck a rod and magnet in there and no flakes or anything. ive been trying this engine off gear change thing alot but no progress. i cannot engage into the gear at all, its just not having it. and your right about the ap1 service parts are all carbon coated.

 

So i talked to the guy who i gave that advice to this weekend. (rowing it into 5th/6th gear)

His trans is completely fixed.

 

billman, when your 6th went out, was it like completely closed off or were you able to get it in just a bit?
