TF999 issues!

Hello Gents! OK I was on my way to work and about half way there I ended up with some slipping from the 999 shifting from 1st to 2nd and a bit from 2nd to 3rd. It was a rapid loss of motivation going from working fine to slipping. I was able to get to work and back to the house under power and it was the same with the trany hot or cold. Sooooooo.... Today I went out and did some tinkering on the jeep and let it idle to operating temp and checked the ATF even though I have no leaks on the ground. It was full, clean and still smelled ok. I had just changed the intermittint wiper switch a few days before and though I might have knocked the shift linkage out of adjustment so i readjusted that and still had the slipping. the slipping only happens as i go over 2000 or so RPMS and the engine get to the point that it would up shift however it wont. It slips and I lose some speed. I can run the RPM's up to about 3500 and take my foot off the gas and then the trany upshifts. Any thought gents?

Check your throttle valve linkage before you drive it again, if it is out of adjustment it will cause hesitation or erratic shifting and eventually burn up your tranny.

Look into adjusting the bands in the valve body. How many miles? I've used Lucas Transmission Fix with great success. Take some of your fluid out first!

If all you need to do is replace the second gear band, its super easy to do at home. The band will prob cost about $15. The hardest part is pulling the tranny.

If it has tracks, tires or tits, its gonna cause a problem.
