My manual 95 cherokee country is not shifting anymore. I was wondering how i check my master cylinder to check if it needs replaced. any help is appreciated!

Does it leak?
Check firewall at pedals.
Does it work better if pumped a few times first?

cmac

just checked for leaks at firewall inside cab and there's nothing. engine bay is same story and the master cylinders fluid level has stayed the same. does seem to help to pump it a couple of times but now in second gear when i let off the gas it produces a high pitched whine. not loud but definitely noticeable.

Might just be a bad slave cylinder. Check it for leaks and bench bleed a new one before installation, if it needs to be replaced.

cmac

what do you mean by bench bleed? and the slave isn't leaking either. i put my finger in the master cylinder and at the bottom the fluid is heavy black. could the slave be bad without leaking?

Change them both, it will give you peace of mind knowing that they have both been replaced.

cmac

ya good point. is it common for them to not leak even if they need replaced though?
also i really enjoy the color of your xj. is it a rattle can job or what? thinkin about doin it to mine when it is goin again.
