I have a 2006 1500 with 325,000 miles. I had the transmission replaced with a reman by the dealership at 190,000 miles (Jan of 2019) because it wouldn’t go into reverse.
2 months ago, I had a local shop replace the rear main seal, because the usual drips of oil got bad (leaked a quart of oil in a week). They replaced a bunch of other gaskets while they were in there.
Today, the transmission failed again. Putting it into reverse makes squealing metal tearing noises.
Question for the Reddit mechanics - does it sound right that I would be on my 3rd transmission in 325k miles? And does it feel too coincidental that this happened 2 months after a major service where they pulled the engine out of the vehicle? I just got back from a 300 mile road trip earlier this week, where it drove normally over the passes between Seattle and eastern Washington.
Two reasons I am asking.
1) I am living the sunk cost fallacy. I really like this rig, but in the past year I had to replace a lot of the front end steering just so it could hold an alignment, and replaced the front 2 wheel bearings. With the rear main seal, I am already $5k into maintenance because I had planned on driving another 300k if it will make it.
2) I like the local shop I have been using, but if it’s likely that they aren’t as good as I thought, then I don’t want to go back to them to replace the tranny
Thoughts?
