Tranny noises
 
Goodmorning! My name is George. I purchased my first Jeep ever. I got a 1990 YJ Wrangler! I got it 3 days ago and had no issues at all..... I took her lightly offroading in deep creek (nothing major) and now all of the sudden my 2nd gear grinds and the other gears are a lil stiff.. Sometimes when im coming to a stop i hear a few loud clunks......... Im lost so can somoebody please give me some me ideas of why it does that... Oh its the 5 speed 4wd 2.5 4cyl model

Thank you !!!

Your transmission has a vent hole on top, it sounds like you drove it in water that was deep enough that the transmission ingested water. Drain and refill it immediately with fresh GL-4 75W-90 gear lube like Redline MT-90 or Royal Purple Synchromax. Or, easier, synthetic 10W-30 motor oil which the manufacturer approved for your AX-5 transmission.

No worries, 75W-90 gear lub and 10W-30 motor oil may sound like way different viscosities but they are not. Gear lubes and motor oils are measured on two different viscosity scales.

Thank you Jerry... I see your very knowledgeable with Jeeps! I did exactly that a few times already.. Now to the next question.. How do I stop that from happening in the future without having to avoid the water???

The only way is remove the transmission and replace the vent with a barbed fitting for a vent hose you'd run up into the engine compartment. You'd have to drill and tap the top of the transmission case for the barbed hose fitting. That means metal shavings you'd have to insure didn't drop down into the transmission.

Personally, I'd just stop driving in that deep of water and find other offroad things to do with my Jeep.

I agree here. I like to use my Jeep as a land vehicle and stay clear of the deep water. I avoid mud and deep water but that is just me.
