Hard shifting transmission
 
Gradually noticed that getting into 1st was becoming difficult with the motor running only. Wasn’t grinding just felt like 1st was locked out. I could get it in by playing with it. Continued to drive for about a month (I know, shouldn’t have). Replaced clutch disk, pressure plate, throw out and pilot bearings. Changed tranny and xfer case oil and found about a soda cap full of shavings on the tranny magnet. The clutch engages about ½ to ¾ of the throw of the pedal now so I don’t think I have a clutch problem any longer???? TJ shifted better but was still difficult so I replaced the slave and master cylinders and bled the system 2 separate times. The clutch still engages but I am now having difficulty getting into 1st and 2nd. There is about 50k miles on this Tranny wondering how long the AX15 lasts and if anyone knows what I could try, short of a rebuild.

my 2.5 TJ does something similar when the transmission heats up after 5-10 min of idling. basically when I stop in neutral, then I want to get in 1st gear or any gear with a syncro right after I push in the clutch, it wont go in cuz the blocker ring is blocking, but if I keep pressing the clutch a big longer about 2-3 seconds wait till the transmission slows down, I can get in gear no problem. as long as I'm moving, I can shift no problem. changed transmission fluid and didnt help, clutch feels good.

I have the same issue with my 2001 4.0L, any ideas on what causes this?

All I know is that when I bought my TJ (w/AX5) it was sometimes hard to get into gear and and had a 2nd gear downshift grind. I replaced the fluid with Redline MT90 and fixed its issues...now it shifts like butter.

You replaced the transmission fluid with redline MT90? Sorry Im new to this

Did you just drain and refill the trans or did you flush it? I ask because you may benefit from a good flush of the trans and then refilling with MT90 or similar fluid.

OK. So I now this might sound weird :doh: but how do you even check the oil on a 99 TJ. I am also having problems shifting and I know that the fluid has not been changed/flushed in a long while. I just bought it in Feb or march of this year. Please advise. Thank you.

Standard Trans does not have dipstick like auto. You can remove fill plug and stock finger in there, should be level to the fill hole. If it hasn't been done in a while, just get the supplies to do it. Not hard at all, just be sure to remove fill plug first before drain plug!
