2004 Rubicon, 42RLE, two inch lift, MML, 1.125 body lift. 5:13s. Bought the jeep a couple of years ago with 58,000 miles. Now has 97,000 miles on it with probably another 20,000 being towed, but not on the odometer. It has always had an issue at very slow speeds shifting down from second to first, have to give it a second to find first. I will probably die with this jeep and have way more money in it than I could ever get for it, but I like it and its perfect for what I have it for. Went by a transmission shop I trust and owner says its probably going to go out at some point and very expensive to rebuild. (Around $3,000). He told me to drive it until it didn’t function anymore. Shifts great under all other circumstances. Has had fluid changed (sucked out, not flushed). Thoughts on the issue and thoughts on the cost of a rebuild from the many experts on this forum. Thanks in advance.
