Death of a good transmission? (Bikini model click-bate incuded)

If you clear the 770 type codes will the ecu throw them again? I ask cuz several weeks ago, my threw a 770 for no apparent reason, I cleared it and it hasn't returned. I realize you have some kind of symptoms but thought i'd mention it could be a false code. Are you sure its the tranny with the hesitation and not the engine? Luck.

I cleared the codes yesterday morning and have since put on about 50 miles and they have not yet come back. Anything is possible I suppose as to whether it's the tranny or engine, but it feels like a tranny issue and then I get tranny trouble codes.

Any chance you've done some other maintenance recently and possibly left a wire harness disconnected (or fell loose). Might be a long shot, but checking them is free.
I haven't done anything recently, but I plan to get under there and poke around, check diff fluid and inspect the driveline soon and look for anything amiss.

Its worth noting that I continued to drive the Audi for about a year and a half with only the occasional clunk that scared the crap out of me- every time I was half expecting to look back and see my transmission on the road behind me. Just my uneducated opinion here, but a slight thump is probably not damaging anything too fast(that's what the shop told me the first time I took my car in, anyways, emphasizing probably). You should have time on your side, unless anyone else chimes in with a crap you gotta fix that right now or set it on fire and claim the insurance warning.

383k? If it was my baby I would start setting aside the money to fix it, but your trucks emotional value to you could be entirely different...

When I was younger and bought my first truck, a good mechanic friend told me a good rule of thumb was that Dodge on average cost about $100/month in typical maintenance costs(usually due all at once when something major craps out). So I took his advice and set up an automated monthly transfer to an account set aside for mech issues, and its definitely saved me a lot of stress and wiped out checking accounts since then. If you started putting aside $50 a month or so, but the time this gets worse or you decide to take a peek for metal shavings you'll have a little slush fun handy.
Yeah at this point even though I'm flat broke, I would either replace or rebuild the tranny if it's truly dying. Even though my truck is pushing 400,000 miles, I can't give up on it unless there is a catastrophic engine failure too. Bailing out of my truck right now would be like dumping Clint Eastwood off at a senior home on my way to see a shitty Vin Diesel movie.

I like your idea about saving some cash each month! While it may seem so simple to just save a little cash each month for future repairs, it really is a great idea that I think I will implement immediately. At nearly 400k, costly repairs are just going to be a fact of life for me.

Cool fluid means cleaner fluid which leads to a longer life for an automatic tranny.

To the OP, I would be happy to get 383,000 miles out of an auto tranny without some kind of major repair. I'd look for a used one pronto. You could drop the pan and ohm out the solenoids, but IMO the effort wouldn't be worth it.

Maybe an R150 swap instead....

Why would it not be worth it to test and possibly replace the solenoid? Is it the cost of the repair vs replacement? Or just more hassle than it's worth if the tranny is on its way out?

I have had solenoids go bad and be the only thing wrong...I would do the simplest and cheapest checks first.

As well, before I did the anything, I would do a lower pressure flush with cheap fluid and then I would pull the pan to proceed with other necessary service. The lower pressure will help clean it out.

Also, tranny codes usually do not occur unless the situation that is causing them happens numerous times. If they did we would be clearing codes constantly, because often a situation that would throw codes occurs in normal operation, but consistently.

For instance, if you are pulling a steep grade, the tranny does not shift out of low in sequence. You don't want it to throw a code every time you pull a steep grade. But if it fails to shift timely every time we pull away from a light we want to see that code. So the designers usually add an algorithm into the code that counts the numbers of failures in a given time...

I have had the same thing in a jeep. But over time the codes throws sooner and sooner and guess what, it was a sensor...89 bucks, or so, not a new transmission as the trany shop informed me. Lessons learned, 1 don't ever power flush, 2 learn diagnostics.
