grinding noise

[lwalker24]

help! new to me, 94 wrangler YJ w/ 84K makes a grinding noise when down-shifting, no matter what speed- transition from 3rd to 2nd grinds. sometimes grinds from 4th to 3rd and during shift into reverse. is this a clutch or a transmission problem?
don't let a mechanic rip me off, how much should i expect to pay to get this fixed?

Does it only grind when downshifting or upshifting as well ? I would check the obvious first. Check the clutch hydraulic master cylinder fluid level, check the gear oil in the transmission, is it at the proper level and clean ? Perhaps it's time for a fluid change. After that I would suspect worn synchros in the transmission or time for a new clutch. Once you know for sure what the problem is, shop around for different estimates from reputable shops. They are supposed to use a flat rate manual which tells how many man hours it should take to do the job. Personally, I would remove my own tranny and bring it to the shop to save labor. Clutches are easy enough to do if you are mechanically inclined. Hope this helps...

Try changing the fluid in the tranny to a synthetic type. There are many out there that help reduce wear on the syncros, and help it shift much better
