The transmission was pulled back out of the Jeep and taken apart for inspection. It was discovered that the chain driven fluid pump on the valve body was bad and only making partial pressure. While the transmission was open the internal wiring harness, torque converter, and seals were replaced. The transmission went back into the […]

LT Swap – Do Not Use An 8 Speed In Your Swap!
Jeep has been in the shop for 7 weeks while working on transmission issues. Hell at this point I could have taken the whole damn engine out, completely rebuilt it, and put it back in, and built an entire Jeep from scratch in my spare time! Instead I am waiting for answers from GM on […]
LT Swap – 8L90e Curse
Jeep is still in the shop. Transmission has been completely dismantled and no obvious signs of breakage or foul play were discovered. The transmission will be reassembled with a new GM 8L90 master seal kit, a new bell housing pump, and a new torque converter. The hope behind the changes is to finally have a […]

LT Swap – More non-News
Yesterday I dropped the Jeep off at CK Customs in Ennis, Texas. Cal, the owner, is a trusted friend that is just about the only other person I will allow to turn a wrench on my Jeep. The list of checks and changes seemed long, but it was all wrap up items on the build […]
LT Swap – Updates
Not much news since the last post. The Jeep is running with the L86 swap, however the transmission is not shifting at all. The 8L90 is not playing nice with the swap and canbus configuration, and will not change valving through the shift range. The Jeep was sent out to Tribe16 to get final exhaust […]

But no liftoff. Yesterday was a good day. I received a base unlock tune file from RPM Extreme. I downloaded the tune and headed out to the garage to write it to the ECU. While I was trying to write the tune I kept receiving errors in HP Tuners Editor for missing protocol. I was […]

LT Swap – HP Tuners
I took some time away from the Jeep to get a few other projects taken care of around the house and also to take some time off. I have been spending 4-5 hours a night and 20+ hours per weekend trying to get things back together since my axles arrived. The Jeep is assembled with […]
The Tow Pig is Back!
In March I took the tow pig to Decatur to pick up some Nitto Trail Grappler 40s that I had ordered for the Jeep. The ride up was uneventful with zero problems. After I loaded up the tires I jump on the highway. Well at the top of the freeway entrance ramp the truck went […]

LT Swap – Crank but No Start
The Jeep was prepped for ignition. All fluids were topped off. The RPM Extreme Jeep feature flash was performed to let the Jeep know some items were coming from the GM ECU, and to ignore fault codes for those items. I was able to set up a few cameras in the garage to record the […]

Oh Yeah – Switch-Pros SP-9100 – Part 2
Ha! I almost forgot part two of the Switch-Pros SP-9100 install! With the dirty work wrapping up on the Jeep I took some time to get some accessory wiring knocked out. I cut all the battery cables to length and replaced the ends with heavy duty heat shrink crimped lugs. The supplied power cable for […]
