As the title says, I now have one totally cooked tranny. I am currently stranded in Sweetwater,Texas. Tranny died 2 miles away from I-20 on US Highway 84. We're currently working on trying to either get a new tranny or figure out some way to transport the truck and the trailer with the car on it. So, if there's anyone nearby us that's able to assist us in locating/purchasing a replacement TH700R4/4L60 transmission in the localish area, that would be most awesome. I'm currently at the LaQuinta in Sweetwater TX. Truck's sitting at A1 shop. Going to eat for now. and I will update ya'll later

Sweetwater, damn your still west of Abilene.
I know a few people in San Angelo but none of them are answering their phones right now. I'll continue trying to get a hold of them and PM you if they can help.
Hate to hear your having problems.

Sorry to hear about your tranny Christopher. The tranny went out in the Wife's Burban last weekend but luckily she was close to home and we were able to limp it to the repair shop with only 1st and 2nd gear.

Wish I could help you out brother!

When we were heading to Lubbock to pick up the car, it seemed like the truck had lost some of the power it had earlier that day. We diagnosed it as a possible misfire, and there was no oil in the motor, despite there being a full quantity in the motor when we started. We picked up the car, and started on our way home. My uncle thinks that it blew out because of the constant misfires causing undue strain on the tranny from the tranny up and downshift erratically from the misfiring. We are investigating possible methods to rectify our situation.

Dam dude what happened to your oil? that’s a lot of oil to use that quick? Sounds like the oil cooler line blew, and if it did you may be looking at a new engine to. Wow you really mey be in trouble.

Is the trany toasted?
Does the fluid smell like burnt almonds?

These newer type tranies are electronically controlled and a real pain to diagnose.
Sorry I am of little help in Texas, I do have a cousin down on the Mexican border but he is useless when it comes to vehicles.

Sorry to hear that. Unfortunately all of my Lubboc connections have graduated and moved on, and the next nearest person I know is in Weatherford.

Let me know what parts you are looking for, I can hunt the local junkyards for you if you need and maybe we can get a rescue truck sent out from the DFW area!

As an update, I am now home, with the truck. We were able to located a Uhaul truck Monday morning to pull the trailer back to Slidell. Technically, the trailer is a 2 5/16" coupler, and the Uhaul had a welded-on 2" ball that we couldn't replace, so we pulled the trailer with too small of a ball. We loaded the Suburban as far forward on the trailer as possible to provide as much tougue weight as possible, and started towards Slidell. We made it home at 3:30am this morning in one piece. My cousin drove the car we picked up in Lubbock home with no plate or anything.

So far, we have not been able to take a moment to pull the tranny and determine the exact damage. My uncle and I theorize that the rear seal on the motor is shot, and has probably been run for a fairly long time with no oil, and that the tranny fluid pump is probably toast. The tranny fluid does not smell like burnt almonds, although none of us have/had great senses of smell. The fluid did not have a reddish tinge to it anymore. It wasn't brown persay, but the color was heading that direction. There is a fairly large quantity of some type of fluid on the front of the rearend and neighboring parts (my "back porch" lights, trailer hitch, transmission rear support brace, etc), but we haven't identified what type of fluid it is, presumably oil, but it doesn't seem to have an oily feel to it....the IMMENSE amounts of dust in Texas perhaps? The transmission is the last year 700R4 before they switched to the 4L60E, so no electronics on the tranny to worry about. My uncle looked on Phoenix Transmission's site, and it's looking like a new rebuilt transmission and torque converter is going to be about $1200 shipped with the 250 core charge. Depending on what we find out with the motor, a new crate motor may be in this truck's future too, if it'll be cheaper than rebuilding it.

I just got a call from my uncle. They pulled the truck off the trailer. To get the truck to roll backwards, he had to drop the driveshaft. So, apparently the tranny is so locked up, you can't even push/pull/drag it in neutral. We were able to pull/push it forward with little to no effort in neutral though. Sunday we will hopefully be pulling the tranny and making a damage report.

On a far-off side note....Sweetwater seems like a nice little town. Not much to do from what we saw, but we were somewhat preoccupied with other things..... I do appreciated everyone's willingness to help me when I was stuck out there. It sucks that noone was able to provide assistance, since I would have loved to have met all you fine individuals, but I made it home.

Well that is a real shame Crawdaddy. So close to Christmas too. If I may suggest...maybe you should look into a donor truck to pinch the driveline out of. Good runner, bad body...You get the idea???

Before the trip started, and before I agreed to use my truck, my uncle and I were assured that any and all costs related to the trip, including breakdowns, would be covered by my cousin. So, all this happens, and he's trying to back out of it, but after a stern lecture and ensuing fight, my aunt and uncle has pretty much got my cousin to actually pay for the repairs. We're going to do the work ourselves, but parts will be covered by him...or I'm kickin' his *ss for welching on his promise. Either way, all shall be fixed, and hopefully fairly quickly so that my dad won't say "I told you so...". My uncle wants to get it done quickly to save me the grief from my father, since he thinks it wasn't neccesarily the truck that caused it...I don't know. All's I know is that I'm dissapointed in the burb. :( However, she's 17 years old and has never had the motor or tranny opened up (ie no head gaskets, intakes, nothing).

Sorry to hear that you're rig broke down. At least you made it back ok, and your Aunt and uncle made it right.

I'm glad you made it back home, sorry that noone could come out and help you out.

I guess it could be a blessing in disguise if you are getting basically a new drivetrain out of it all, and you aren't having to eat the cost!

Here's hoping for a better run of luck leading into the new year!

Well, hopefully everything will work out and there won't be any hard feelings that last on for years to come. These sorts of things are expensive at times and people can kick themselves. It's just one of those things though. :neutral:

I have been hearing a lot of bad things about the 700R4 since I've blown this transmission. One thing that was said was that I was lucky it lasted almost 200,000 miles; they only last about 100,000. Another thing I heard was that they are horrible for towing. On the flip side, I've read things that said that if you build them up right, they're nearly bulletproof. So, who's right? If I need to build the tranny up any, what should I do to it and should I bring it into a professional, since this will be the first time I've worked inside of a tranny. My cousin should be ordering the new one tonight from Phoenix Transmissions.Thanks.

They're both right.
Early 700r4's had a bad rep for reliability, in the late 80's there were improvements made, the bad rep stayed with the transmission tho. All 700r4's dont like to tow in overdrive, they overheat easily under medium loads (even when not in overdrive), and generally wear faster than comparable transmissions (due to the heat).
The improved 700r4's came out sometime around 1988 (not sure of exact time frame), used the same exterior case, input pattern, and output pattern but had internal improvements that improved shifting, cooling, and strength which resulted in longer life. I believe all reman or replacement 700r4's have the upgrades incorporated. If you dont already have an aftermarket trans cooler on the truck it would be money well spent for your new 700r4.
Even with the improvements the 700r4 isnt the best transmission for towing, its a medium duty transmission. There have been some 700r4's that have been run behind 400hp+ engines, or in full time tow rigs and lasted a while, but not without lots of maintenance in the form of frequent oil and filter changes, larger pan/increased trans fluid capacity and a larger aftermarket trans fluid cooler. Even if you dont plan on towing a lot these mods help reduce wear on the 700r4 in everyday driving conditions.

the 700r4 in my 89 burb has 192k on it, and it did well towing my big '76 Buick from Nebraska. it does have an external cooler on it. (didn't tow in OD) avreaged 60 mph there and back,
although take offs were a bit slow ;)
