    Transmission codes immediately after coolant flush

    Hey, all. I have a 2006 TJ 4.0 auto, 101k. Bought it ~2 years ago with 92k. This jeep was a bit neglected when I bought it - needed all new bushings, shocks, control arms, track bars, plugs, tires. I've changed most fluids so I know what's in there. It's never thrown any codes or run poorly for...

    32RH Shifting Issue

    I have a 32RH in a 2001 4.0. I’ve had a recurring gremlin that I just can’t fix. The issue is essentially that it won’t stay in 3rd gear under certain conditions. It will shift into 3rd and coast in 3rd just fine. And it seems to be shifting just fine. But under any sort of throttle, even just a...

    Down the rabbit hole (not the transmission after all)

    Borrowed my buddies truck and got the jeep back to my house. Will drive on/off the trailer, seems to be running fine. Can’t pinpoint where the fluid came from under the jeep, other than I know it’s the transmission somewhere. It looks like where it mates to the transfer case? It’s hard to see...

    2004 Wrangler 4.0 42RLE automatic Hi all, I've made a post about a year ago now of a noise with my Jeep. I was never able to figure it out and life has gotten in the way so it has stayed in storage on jackstands. Today I took it out for a drive to jog my memory of the issues it was having...
