Ok, so 2 years ago, I had the plastic shift fork replaced. The shop put a metal fork and plate back in the case. A few days ago, the pump in Tcase went out, so I had to replace the pump, some bushings and gears. I drive home from the shop, park it overnight, get ready to leave this morning to go trade this money pit in, and as soon as I put it in drive and push on the gas, I hear a LOUD clunk underneath, and now it acts like the fork busted again, wheels act like they are binded, and it will not shift into 4 low, it just blinks.....so I had my buddy come pick it up on his flatbed and take it back to the shop, and of course they are closed on the weekends, so I left it there, and put the keys in the drop slot....any ideas as to what happened this time?

 

typically you go look where the last work was done.
ah, open it up huh
