I've put a few hundred miles on my new-to-me 03' Sahara since I got it. Mostly off-road but I did drive it to town a few times for fun. It took a few hundred miles for it to happen the first time but I've had the transmission "miss" the 2-3 shift a couple of times. When it happened the first time I let off the throttle and it bumped into 3rd no problem. I convinced myself it was a fluke due to me bumping the shifter or not having it exactly in the right notch. No check engine light - nothing else to cause concern. The tranny generally shifts perfectly - no slipping at all or any other oddities. Well, it happened a couple of more times since then separated by dozens of miles and a couple of weeks of sitting unused. I kept driving it but started suspecting my shift solenoids.
Last weekend just as I hit the pavement from some wheeling the passenger brake caliper started to seize. Within 5 minutes of my brake caliper seizing it really went haywire. Kept missing the 2-3 shift and seriously made me think I was going to be stranded. The check engine light came on...the whole bit. Doing the key-trick while waiting for my brakes to cool off I found a P0700 code. The check engine light stayed on but it returned to shifting perfectly(including overdrive) when I got on the pavement to scurry home w/my tail between my legs.
When I got home and connected a regular(generic) code-reader I got the P0733 code(3rd gear shift rpm) too.
So to the best of my interwebbes browsing ability it appears my solenoid-pack is failing. The transmission was rebuilt at AAMCO at 60k miles per the carfax report and it's just over twice that many miles now(130k-ish) Should I risk putting a new solenoid pack on it now myself or bite the bullet and get a rebuilt tranny? I can swap the transmission myself but certainly don't think I can rebuild it myself so I'll have to buy a rebuilt one($2k) if I go that route. Which will put my other upgrades off for a while. The Jeep hasn't been abused afaict. It seriously appears to have spent it whole life on pavement under adult control.
