Slipping, crunching noise, when putting in reverse. Flush Transmission fluid?
Noticing a some slipping and crunching noises when putting my 95 Wrangler (4.0l, 6 cyl, stick) into reverse (not in any other gear). Read a bunch of previous posts, which mentioned flushing out the transmission fluid, as a possible fix. May not be the only thing to do, but I would give it a try on my own.
Question is do I need to drop the pan and swap the filter? My hayes manual, only mentions removing a single bolt and pumping out the fluid. Nothing for stick shifts on the whole pan, filter and flushing part.
Can anyone shed light on this? What are you thoughts on how to proceed?
Mine grinds if I press the clutch and go straight to reverse. If I hold the clutch for a minute it doesn't grind, and if I go into first or second first it stops something from spinning and goes into reverse without grinding. Don't know a fix but it hasn't bothered me that much yet.
Mine hasn't crunched in reverse but in 2nd and 3rd. It has gotten horrible and loud and a lot of times won't go into gear. Mine also seems to slip when starting off going forward or reverse. It shakes and buckles and you have to give it more throttle to try to stop it. However, I'm replacing the clutch hopefully tomorrow and have new Royal Purple transmission fluid that is going to go in soon. Just a word of advice, don't let the problem slide because you found a temporary fix (holding the clutch in and pausing before shifting). I did this and I can't drive the Jeep until it gets the clutch for fear of breaking transmission gears it grinds so bad. The crunching might just be the tranny (you can't speed shift), but when you say slipping, it makes me think of the clutch.
As far as i know, neither the AX-15 nor NV3550 have synchronized reverse gears. A bit of crunch is normal if you don't let it spin down or move into another gear first. A new clutch isn't going to affect that.
You do not need to drop any pans, and there is no filter on the manual. Just pull the fill plug, pull the drain plug, and go from there. Not sure what Haynes was smoking when they recommended trying to pump out the fill hole... there is a perfectly serviceable drain plug on the bottom...
