Looking to put my 71 on in the next month or so, and yes, I think that will be the end of mine too! LOL

Idk bud. I think the 4:30 gears help alot to reduce the load.

Tow X turbos and heavy loads. Still going strong. Although I did change my fluid at 65,000 lol. 125,000 on it now.

Rivets are the new duct tape.

Bought mine with 76-77k tuned at about 78-80k, now has 116k. Ran KEM 345 the whole time. I did studs and 71mm turbo, 60hp nozzles at 112K, I dd on the 345 and race on xrace since build. My stocker is still hanging in there with close to 40 drag strip passes, and lots of street launches all on 35's.
I also have pmf bars since 92k maybe that has helped.

Bought mine with 81000. Been spartan tuned since the week I bought it. Has 104000 now. Still on the stock tranny. Been to the track a few times and done a few dynos. I drive the piss outta mine. Feels like clutches are starting to go on me though.

128,000 mi on mine, and still holding strong. Tuned via Innovative since ~87k mi. Run Ex Race 80% of the time, Ex Street the other 20%. I use Race lock trans tuning on both files.

Those 41k miles tuned have not been easy, At least 30 passes(probably about 5 when I had 37's, 15 on my current 35's, and 10 on street tires) on the track, a few street launches while loaded with passengers, a couple dyno days, an scca rallycross event, 2 ~100-150yd long pedal to the floor burn outs, and plenty of offroad abuse. I can't believe it's still alive, and strong at that. Have had PMF traction bars for around 10k miles now, which I would say helped a bit.

47k on my '10 right now with about 11,000 tuned. I'm going to say 25 track runs and 5 pulls on it all with 35's. Did find some shavings on the pan magnet when I replaced the filter and added a ported solenoid. TC numbers are starting to creep up on me around 15-20 at full lock so a tranny will be coming my way in the spring. I'm sure I'd be fine for quite sometime, but with a few more power adder goodies planned in a few months it'll be peace of mind if anything.

My son bought my 2010, and he has started to have some problems as of recent. It has a afe, dpf delete, egr delete and SCT with Eric's tunes. It is now sometimes not shifting into OD under hard exceleration. And occasionally it seems to lock into a higher gear when he goes to take off. (Lots of smoke and no power)

Do you think that the upgraded solenoid would fix this?
