Transmission woes...again

The factory transmission lasted 205,700 miles. I replaced it with a BTS at that point. That one lasted to 285,988 with just 80,298 miles. I sent it back to BTS for fixing. Now that one is gone at 425,000 with 139,002 miles on it. I haven't abused these transmissions. I've put in the newer larger oil coolers and I rarely see temps about 160...most of the time I'm in the 140 range due to the colder area I live in. I've kept up consistent fluid and filter changes every 30,000 miles and have only used BTS recommended Shaeffers All-Trans synthetic fluid. I've probably only towed a total of about 2500 miles in all the years I've owned the truck. Its been my daily driver.

Recent saga is that it was running fine up until this morning when out of nowhere it will only engage into reverse. Any forward gears it will just rev up and not move. last summer out in Arizona it puked out fluid out of the transmission just sitting after a day in the heat while visiting there. Its done this before with the last transmission. Never leaks until I get into Phoenix in the summer months and parked it. Leave it for a day or two and there will be a large puddle of fluid under the truck. I fill it back up and everything is good. It has lost about 2 quarts from this heat related expansion.

I thought I was doing myself a favor by going with the BTS transmission but my experience has not been very good up to this point. I'm not sure what to do at this point? What are people recommending for transmissions these days?

Well, that's disconcerting, that many BTS rebuilds being short lived. Did BTS do the change outs?
I did the installs myself both times and was sure on the fill amounts per Brian's instructions, etc. The first time one failed they said that it looked like I had used some sort of detergent additive to the fluid. I hadn't and I was the only one to ever service the truck.
The transmission is out and will be sent back to BTS next week once I receive the shipping box from them. Brian mentioned a problem that they had with some of the old purple Precision (???) brand torque converters giving them problems and maybe this had something to do with its failure. These were converters that went into their transmissions some years back. Mine second one was installed in 2015. He wants to open her up and take a look at things to try and determine what was going on. I'll keep you posted on what turns up. Looks like I'm dead in the water for at least 2 weeks...this is my only and daily driver.
We actually live in Mexico (full-time missionaries down there since 1987). We went up to in El Paso, Texas for a 2 day shopping/supply run when it happened. We're very grateful it happened here and not out on the highway somewhere. We have a safe, comfortable place to be while waiting for it to come back. We're thinking of jumping on the Amtrak to Arizona to visit some family there while waiting. Once there we can borrow a car. Friends let us borrow their car the other night to get some groceries with (I was getting tired of Dominoes pizza for every meal). We're good.

We're down in the lower section of the state of Chihuahua. Look up Copper Canyon and Tarahumara Indians and you'll see the general area. I'm originally from Phoenix.

Oops...that puts you into the city of Chihuahua. Do this search instead...Guachochi, Chihuahua, Mexico. That'll get you within 10 miles of where I'm at.
Should be getting the shipping box tomorrow so I can freight the tranny back to BTS. He said that he'd get right on it...I sure hope so as I'm a long ways from home :)

The transmission got to BTS on Friday. I called yesterday to validate its arrival and was told its on the docket. In the meantime we did take the Amtrak over to Arizona so we can see some family. As soon as Brian opens it up and all he's supposed to call me to discuss what he finds and what will need to be done.

The other two times I did this before I purchased new 6.0 coolers with the install. This time I'm wondering if its really needed (replacement that is)? I only ask since in none of the lines, nor the cooler have I seen any sort of shavings, etc. I've blown through the lines and cooler with air (dry, without any cleaning liquids) to see what comes out catching it into a clear container and there has been nothing, zilch, nada. Being an early 99 my truck doesn't have the radiator cooler but relies completely upon an exterior cooler so I don't have to worry about that. I did it before as cheap insurance and especially the first time to simply upgrade to the larger cooler but frankly I'm wondering if its really needed or am I just being stingy???

You know, I rarely tow and my normal driving temps are usually around 140-160. Even when I come up to Arizona once in a while I in the summer I might see 180. All that to say that I'm not too concerned about the need for even more cooling. If my situation were to change or if my radiator pukes out, then I'd probably upgrade to the one with the built in transmission fluid cooler.

I did go ahead and order a new 6.0 cooler today :)
The new (Dorman) cooler arrived. Might add that it was very well protected in the box and looks great. We also received the transmission back from BTS on Tuesday and an hour later it was up in the truck. It did take the rest of the day to get everything else all hooked back up and then yesterday morning we filled her up with fluid and took it for a test drive and everything is working as it should. I'm still waiting for a call back from Brian to get the lowdown on what he thinks went bad on the last one. He did take very good care of us and all I can say is that I am very happy that I went with him years ago and can only encourage others to do the same. I'll post again once I hear back. In the meantime it sure is good to be back on the road again. We'll be heading south again tomorrow, Lord willing.

No, he didn't. Since we're back home in Mexico I'm not sure he will be able to reach me.
Yes, we use Whatapp quite a bit. I might do that.
I've yet to personally talk to Brian but by email his wife let me know that he said that the center support bearing went bad.
I actually emailed his wife and she asked me to try and call sometime. I probably will in a few weeks when we're up in the States again.
