Mileage on tranny.

[cbodie]

I've got a '96 SR5 4WD with automatic tranny and 194K miles on original tranny. Any testimonies on how many miles you get out a auto tranny on this vehicle usually? It seems like any high-mileage vehicle with auto tranny usually goes out eventually. I'm just trying go gauge if I'm near it or not.

It depends on how well it's been taken care of, have the fluid and filters been serviced regularly, how many times has it been over heated, theres a lot more to it than just mileage.

I'm at 200,000 original miles on my auto-tranny. No slippage.

I follow the service recommendations for fluid changes. I did a full service (machine) flush at 175,000.

I don't have high expectations, I think it is pretty good to have made it this far. If it starts to go then I will look for a used one.

A/T tranny's usually go at 195K.
j/k, as long as you don't beat the sh!t out of your truck and check the fluid you should be good.

Mine is at 240k miles...no problems at all.

Ha ha ha ha ha ha.

I might flush-it. Not sure of servicing on this one. I'm off the fence and ALL IN on an E-locker. I have no factory wiring so it's eBay, welds, tapping, grinding, and Radio Shack. Not trying to start another thread, just saying. Told the wife It'll cost around $1200 (ARB) so a $600 job will seem like a trip to the dentist. See how that works: so lies, just prepared statements. Use this tactic if needed, free of charge. :banana:

Around 250,000 you can expect a rebuild to be needed. Sooner if it has been worked hard or abused and a little longer if those are all hwy miles and serviced regularly.

Some have mentioned, "Just don't mess with it! You'll cause more harm than good if you mess with it."
I've heard that a few times when people talk about transmissions, though I'm not sure if it's good advice or not. It appears that if one flushes the tranny, they'll potentially remove metal "fragments" which could cause more damage later. The biggest argument I've heard for not flushing is that one could cause a fluid leak. That's a lot cheaper than a tranny, for sho.

So, should I flush the tranny, or just let it be?

My sister's 1997 Limited has 243k miles on the original transmission. It's been flushed a couple times by the dealer, and I bypassed the factory cooler when we bought it. Shifts perfect.

I'm going to drop the pan and change the filter before this next fall, if everything looks good (no chunks in the pan), I wouldn't be surprised if it lasts well past 300k.

Transmission fluid does not last forever. Power flushing has been known to damage stuff, but a T-Tech machine that uses the transmission itself to pump the fluid works great. The other way to do it (that most people here on the forum use) is to simply drain and refill the fluid. Drive 100 miles and repeat. After 3-4 drain and refills you pretty much have all new fluid. You need to take the pan off and replace or clean the filter though.....just draining and refilling doesn't help the filter. I would take the pan off, replace the filter, clean the magnets, etc. Then drain and refill a couple times and call her good!

One of my Mechanic friends that works on consumer vehicles, had a T-100 in his shop last year. It was there because the original T-belt had finally failed at 360,000 miles.

It had the original 5VZFE engine, and A340 auto tranny. After replacing the T-belt, the engine sounded great, and the tranny shifted fine, despite having slightly discolored ATF. The truck was a work truck that looked to have been abused every day of it's life, and considering the original T-belt, hadn't been too diligently maintained.

Who knows how long your trans will last. But based on how reliable these trucks tend to be, I'd be inclined to maintain it, and I'm guessing will probably last for many more miles.

I read the Tutorial on the Reference Pages of this forum for 3rd Gens on how to flush the tranny and replace the filter. That looks like the way I'll go. I've done work of this complexity before.
So, it sounds like a flush is warranted, and good measure.
Don't think I need a cooler, though. I'm not towing too much, and I'm basically stock wheelin', with a "paid for itself many times" winch.

You don't really need a cooler if you don't live in an extreme weather environment AND if you recently replaced your radiator.

IF you are still running the factory radiator then get a cooler or replace the radiator ASAP!

Just a bit of advice, google "pink milkshake" there seems to be several a month on these forums and that is just within the off-roading community.
