AX-15 smoothness?
I just bought an 87 YJ with a supposedly rebuilt AX-15. The tranny
seems a bit clunky between gears, not real smooth, it seems I have to pause a bit between gears to let the synchros engage. I don't hear any grinding. Is this normal for an AX-15? Thanks -- o_o_o_o /| ,[_____], |ŻŻŻL --O|||||||O- ()_)Ż()_) ŻŻŻŻŻ )_) |
Re: AX-15 smoothness?
First determine what you have for a transmission:
http://www.off-road.com/jeep/swb/articles/specgrid.htm Although it could have been converted. You may have a sychro problem, but usually with the early YJs the hydraulic clutch fails to completely disengage.

Re: AX-15 smoothness?
Yes it is an AX-15.. it has been swapped in from a 90

Thanks I will try that. I assume the process is similar to brakes...

Re: AX-15 smoothness?
Yup, and like brakes don't let the reservoir run dry, and there's
sometimes a loop that runs above the master that sometimes holds an air pocket, that I bend down and crack that fitting and find bubbles.

Re: AX-15 smoothness?
Make sure it has the correct fluid in it - GL3 not GL5 ( I think the sulphur
eats the brass synchros). Or use Redline MT90.
