Hey folks. 92 xj 4.0 automatic.
Started encountering this problem recently where everything operates fine driving around town (power feels fine, revs normally, etc), but when I get onto the highway and my trans shifts into the final gear, it feels like it’s bogging, and won’t rev over 1900 rpm. When I stab the gas it’ll downshift and allow me to get back up to speed, but once I get there and allow it to upshift again, it’s back to bogging again.
I was having fuel issues recently, and improved the no start problem with some new injectors. I thought this may be related, and premtively ordered a new fuel pump, filter, and regulator, and tried to avoid highways when possible. Today however, after smelling a faint burning smell, I decided to check the trans fluid level, and it was pretty low. Added more fluid hoping this would resolve the issue, but no luck.
Guess I might as well install the fuel system components, but before I throw away money, I figured I’d hop on here to see if anyone has had any similar issues or has any insight for me.
Additional information that may or may not be relevant:
Stutter/ rough idle.
Car occasionally will only start in neutral (assumed NSS)
Recently muffler rusted out and currently has a hole in it while saving for new cat back
Fuel gauge/ speedo non functional
Pretty noticeable “thunk” when putting car into drive or reverse. Not U joints.
I know I’m an idiot and should have checked tranny fluid immediately. Really hoping I didn’t fry the trans. Any advice would be greatly appreciated. Thanks for your time.
