shifting

I bought an 02 Sahara 4.0 automatic. When driving the upshift indicator (yellow up arrow) on the dash comes on when it’s shifting gears… when I get to I guess the last gear around 40mph the arrow comes on and off and on and off a few times over a few seconds and it feels like the jeep is trying...

Hey everyone! I need a mechanic in the South Florida area for my 06 Rubicon. I used Planet 4x4 before and was dissatisfied. I'm looking for a shop that can diagnose the shifting problems - the jeep is an automatic, but inconsistently refuses to shift from 2nd to 3rd) - as well as a mystery...

I’ve not been able to find a discussion about this yet so if there is one, my apologies. I have a 03 Wrangler 4.0 and recently I’ve noticed that when engine breaking, primarily in 2nd gear, and slightly in 3rd gear, a metal rattling noise can be heard until the jeeps rpms catch up to speed. It...

First off, I think I've read everything available online about 42RLE shifting issues, PCM problems, Wranglerfix fixes, etc. Unfortunately I haven't seen anything similar to the issue I've been experiencing, which brought me to become a member of this great forum (long-time lurker). My '06 LJ...

2002 4.0 5psd ~159k miles. Recently and regardless of what gear I'm in or if the engine is on, when I push the clutch to the floor it sometimes hesitates coming back up. It feels and sounds metallic, almost like when you lift off the latch of a yard gate and the latch is worn and gets bound and...

2005 SE Auto 4.0L 65k I was driving earlier and when my car shifted something felt off. It felt like it was erratic and like it was shifting too early. It seemed like there was a loss of power and while I do have 4.88s on 35s, I’ve never felt it shift like this before. I had someone who was in...

2004 Sahara 4.0l 42RLE Auto 199k miles From gear shift 2 to 3 The rig acts like it can not decide to shift or not and lurches in power over and over again until something catches. I have a 2.5 in suspension lift with no SYE installed. Is this a sign of the tranny going bad or something else?

Okay. So we swapped the transfer case. It did fine for a week. Then we loose 2.4.R. It's like they vanished. I did pull back the boots and shift through the gears. But the neutral seem back and when put into 3rd there's like and inch clearance above it. Anyone know? Suggestions? Looking...

Hi everyone I am new to this forum but I have a question about my auto transmission on my 2000 Jeep Wrangler 4.0 sport with 185,000 miles on it. I have had all fluids drained and filled including the trans. I have just recently felt that when I take off from a stop it seems like it shifts really...
