Rebuilt transmission not shifting out of first gear

Does it have a lb?

Reverse too? Try 4-lo In reverse and see if it gives you the same issues as 2WD reverse.

Still sounds to me like a shift linkage even though yours looks about right to me (it’s almost midnight here in WV and I’m crawling around under my jeep😂)

4 lo in reverse gives me no issues and actually drives how 2hi should feel I did my test shifting t-case by hand. It’s definitely in the right gear. Also in drive and reverse the jeep starts creeping at 1200 rpm @hear @Christian.mers

I’m planning on replacing my kickdown/throttle cable. And heavy dusty t-case cable linkage and take jeep to shop Monday. I’ll respond back to this thread when those 3 are done or if I get this fixed. Thanks for everyone’s help and feedback @macleanflood @tr21triton @hear @Christian.mers

Sorry I wasn’t getting back today. Take the jeep to the shop for sure but check out that procedure, I had messed up my throttle cable and I was balls to the walls to get it to move from the stop and I followed the procedure and some of that plastic sleeve did end coming out and you’ll hear some clicking as you make your way to WOT (Wide Open Throttle) and see the plastic conduit coming out towards your cable end

Hey @Christian.mers @hear what do you think of this.. I read another forum with somone else having similar sluggish acceleration issues as me he said it was his crank shaft position sensor. When I was picking my transmission up from transgender shop the guy said “hey it’s prob not good to leave your cps sensor on the transmission” when I brought it in. This just popped in my head. I looked at this sensor right now and I think it may have got fried or melted. He said after he replaced his cps sensor his jeep could climb a tree. If you look closely you can see the wire got melted pretty bad enough to melt the shielding in half

I needed to replace mine. When I would go to accelerate it was absolutely sluggish, some things I noticed would that I would absolutely lose throttle response and when I pressed the accelerator my engine would pop pop pop like it was backfiring, slow down like it was in limp mode and I’d have a huge loss of power and wouldn’t return to normal throttle response till I slammed to WOT throttle. I noticed I really needed to look around when I was driving up a great West Virginia hill and someone pulled out in front of me and I had to slow down immediately, I had to shift into 4-hi then 4lo to even get enough power to get to the top of the hill and that’s finally where I realized my ignorance and laziness was going to be the death of my jeep.

Testing it:
Disconnect the plug and check resistance across your two signal wires (I believe the range is 200-1200 Ohms)

Also check continuity on sensor and chassis ground

Check voltage when cranking (Should be around 0.5-1.0 AC V when cranking if I remember correctly)

Check wiring for issues too

Do you have any issues at idle? It doesn’t sound like what I was experience or the classic signs of a CKP issue, especially if your jeep is starting up no issues but it’s always good to rule everything out

Another thing to note is that I got no codes even with the awful state of my sensor plug and wiring. I touched the plug and it fell on the floor so that should tell you all you need to know. It was only an intermittent issue and I had the issue since December last year but it didn’t give me trouble for a couple of months then happened a few times and then didn’t give me trouble.

That’s sensor takes so much heat soak in the area it’s located. it’s unbelievable. For loom just look at harbor freight for 1/4”

That’s just my take on the CKP sensor issues that I experienced

Yeah and mine has no problem idling
UPDATE: jeep is in transgender shop. Long story short they told me that the fluid is burnt. And yes, this is after I installed the rebuilt transmission myself with new fluid. I removed the transmission myself and brought them The transmission. I Picked up the transmission and installed it again myself It was very hard to believe because I have not driven the Jeep at all, I have started it and put it in drive and reverse and tested this in my driveway. I never once took the Jeep out for a drive after installing the transmission. They are telling me that my throttle cable was misadjusted. And because I had the engine running while the throttle valve cable was misadjusted, the hydraulic pressure was off and caused the fluid to burn. This was very hard for me to believe but at the end of the day the shop recognize that I paid almost $3000 for this to be done and they are saying since they smell burnt fluid, they are going to remove the transmission again themselves and make any adjustments that need to be done or replace any parts that may need replaced again. They’re telling me that I possibly could have burnt my clutch but nonetheless, I brought my Jeep back into them. They are going to drop my transmission look at everything and replace any parts that may of got messed up during my install. (Free of charge) this being my first transmission removal and install. I really appreciate that. They are going to fix and replace any of my possible mistakes. This is seriously one of the coolest transmission shops for doing that knowing that I could’ve made a mistake.

They say it will be done this Monday. I ordered a new kickdown cable and a transmission heavy duty shift cable. I will update when these parts are installed. 👍

Lmk what you think😂 @Christian.mers
I sure am learning a lot :(
 

I also still have these YJ windows..I believe there yj windows. I’m trying to sell them as I have no use for them. I’ll sell them cheap, lmk where I should sell them @hear @Christian.mers
 
Sounds about right, fluids can get hot spots without even driving very many miles. That cable also really does control hydraulic pressure so they weren’t lying to you about that. Even with that test of putting it in reverse and not really driving and your cable being messed up is definitely enough to let the crutches slip and causes issues.

I really should’ve thought about mentioning it to you and mentioning that you should definitely check that cable as a first step so that’s on me but I think it’s amazing that they are offering to completely fix it despite installer error. We all make mistakes and that’s part of learning

As for selling things on the forum, you can scroll down on the homepage and find the section that is labeled “parts for sale”

Yeah, it may also be because they manager “Paul” was telling me when he was my age. He had a very bad experience with a transmission shop and we joked about how us guys, when somthing dramatically pisses us of enough, once.. can literally change our entire career choice for the rest of our lives 😂 so I’m sure he gave me a break but still i am glad they are doing that
 
I feel what Paul is saying, I’m 18 years old and going into the Helicopter repair and maintenance industry. I completely understand how one thing can make the world of difference. Just 2 years ago I wanted to be a rescue diver and save people out in the ocean until I got some real world experience and was actually put face to face in a situation where someone was drowning and I was the only one around. One of the scariest days of my life and about half way through I thought I was going down with him, I won’t do that to myself again so I decided to go the opposite route and save people in the sky.

Not to be a Debbie downer and obviously transmissions and swimming are two different things but I’m a big analogy guy and that’s what I found to be a similar experience of my own to what Paul is saying

That’s freaking sick, I have a similar story, with my most recent job lol, I’ve been doing rooftop solar installs for 7 years I turned 24 this year, somehow got a high voltage power plant job, not to mention I hadn’t even graduated high school, had to drop out, to work and pay bills, somehow I’m making 100k a year working on substations, 500,000volts, and giant school bus sized inverters.. in the endless solar fields you see on the way to Cali. 35,000v inverters. Training was ass, somehow 2 months in no one mentioned to me to turn off the AC breaker from the transformer. Accidentally touched a busbar with my left pinky finger and 400v of AC went through my left pinky finger, through my chest, and to my right hand pointer finger. Scared the fuck out of me. When to hostpital and they said I’m cool but chances of heart conditions in the next 5 years increased by 60%. I stayed at this job for 2 and a half years before leaving because everything I did scared me. That shit ain’t worth it no matter how much I’m making. Was just scary.now I’m looking to become a game and fish officer here in north Arizona🤙
 
It’s crazy how one accident can truly change your life. I think it was definitely a good call to leave that job and pursue something that didn’t constantly scare you.

I couldn’t imagine making 100k a year. I make about $3,000 a month gross income working about 50 hours a week. I’m satisfied with where I’m at currently but I’m a big fan of continuous improvement and a big fan of having goals and ambitions.

I’m wishing you luck becoming a game officer and with your transmission. If you need anything feel free to let me know
