Hey guys, any thoughts on this:
I just got a 97 TJ with 4.0 and AX-15. Everything has been running very well, but there were some signs of lack of maintenance like plugs worn down to 0.045" gap.
This past weekend, I checked the fluid in the tranny, and it was very muddy looking. There were no issues with grinding or anything else. When I changed it, there were very small filings in the fluid. Nothing surprising.
Based on the feedback on the forum, I put in full synthetic 10W-30. Pennzoil because it was available.
After changing the fluid, it now grinds a little bit every time I put it in reverse. No other issues. Any thoughts on the reason for the grinding?
I plan on replacing the fluid again at the next oil change since it was so far gone. This time, I'll try the Redline that folks are also recommending. Any other advice.
Thanks for your time!
