AX-15 help, grinding

I jumped my XJ sorta. lol. Then after that I've been having Tranny problems. It makes a almost a grinding noise when in 2nd gear, Its hard to get into 2nd gear and if I let off the gas while in 2nd it will make a grinding noise, but not the normal grinding noise it would make with bad clutch work. It also grinds going into 4th gear and this happened before the jump.

:scottm:change the tranny fluid to redline mtl if you havent already done so much improved my shifiting troubles in my old ax15 tj.

Your grinding the synchros or grinding the gears, both are bad news.

Drain the box, check the chunks of metal. Yellow chunks are not gold, the other chunks are not gold either.

Remove the transmission, rebuild or replace.
