I have a Toro Powershift 828 that got stuck in reverse only. I took the transmission out and clean it out and put new low temperature grease in it. Everything looked fine and all gears moved as they should in forward and reverse. I put it back together and it worked fine. The next time out it went in forward fine for a short time and then when I shifted into reverse and then back to forward, it was still in reverse even though the shift lever was in forward. Any ideas?
