Hi Guys,
Followed this forum for a while, but first post. Warning - long post ahead.
A bit of history about my Jeep. I bought my 97 wrangler sahara 4.0 auto in November 2018. It was being sold after being parked for two years due to erratic shifting. While looking it over I discovered the TV cable bracket had come loose, so I was certain that was the issue. Got the jeep home and started work on it. Re attached the bracket and put in a new cable for good measure. It ran fine through all the gears although I couldn't get it to hold a gear past 4000rpm. At the same time i noticed there was a slight leak from the auto sump.
Fast forward till this last week. The jeep had been parked for weeks as I was doing other work to it and waiting for spares. We moved house and I needed to move the jeep. Started driving from the old house but as soon as i went round the first corner the auto started sliping. Checked the level and it was low. I topped it up and it shifted fine till the new house. After using it for a few days I decided to do a filter and ATF change. The sump had some sludge in it and the filter clogged up but not too bad. Put the new filter in topped up to the correct level. I did find a very concerning head for a nut in the sump though.
Decide to give it a test, goes into reverse no problem, put it in drive, it starts to whine and shudder, i give it a bit of gas and it feels like its not in gear. I decided to give it a flush, disconnected at the cooler outlet, start it in neutral, nothing comes out. Disconnected at the inlet and it comes out fine. I blew air backwards though the cooler reconnected and tried again. Pumped through fine, checked the return line to the box and it was clear. Flushed with 12L.
Checked the level and gave it a test. Again, reverse perfect. Put it in drive, slight delay then engages good. As soon as i give it a bit of gas, feels like its slipping with a bit of juddering, build up to 1500rpm and it starts taking better, over 2000rpm as it should be. Took it round the block to see how it goes. Performs the same though all the gears. Pull back into the drive and suddenly loose all drive and a faint whine can be heard. I checked the cooler outlet again and pumping fine. Double checked level and spot on.
I'm lost with where to look next. There are no transmission shops close to me and a 2nd hand box is close to $3000 here.
All ideas welcome.
