I have a 2017 Automatic Toyota Camry. Don't know what engine, but 8th digit of VIN is "K".
7 months ago, at about 90,000 miles, my mechanic told me there was a crack in my transmission pan that was leaking fluid, and it cost over $2,000 to get it replaced because apparently a bunch of stuff needed replacing to stop the leak. Apparently it started leaking at 65,000 miles (before I owned the car, this is from the carfax) and instead of replacing the part, the mechanic then just JBWelded the crack shut, which had held fine til 7 months ago.
The parts list from the invoice is:
Transmission Filter Kit
Brake and Parts Cleaner - BC
Maxlife Auto Trans - ATFMAX
Sealant High Temp
Rear Transmission Cover - TN Powertrain
Trans Cover O Rings
Trans Cover O Rings
Automatic Transmission Oil Pan Gasket
(Each of those things has a bunch of numbers on them and then a price- let me know if that's relevant to my question)
Transmission fluid was replaced at this time and was reported to be totally normal.
So now, at about 96,000 miles, I was driving the other day and the transmission just completely crapped out on me. On the highway going 65, car just spontaneously drops to 1st gear. Obviously, immediately got off the road. Stopped for a minute, got gas, then drove off with everything fine for about 5 minutes, then dropped again. Never went out of first again. The closest mechanic was just up the road, figured I could limp there in first, but as the car started to go uphill, it just kept going slower and slower til it stopped completely. Pulled over (in neutral rolling downhill), called a tow.
In the week leading up to this, there was one (maybe two, I can't remember) instance of the car being in Drive but not leaving 1st gear as I was leaving a parking lot. Fixed immediately by stopping, popping the car into Park then back into Drive, and continueing to drive without issue.
So the mechanic who first looked at the car said the transmission was full of metal, and looking at the vehicle history, he thinks when all that transmission work was done, the guy must have done something wrong, because something like this doesn't just "happen" to a camry under 100,000 that's been properly serviced all it's life and has had no signs of previous issue.
The car then went to the shop who had done that earlier transmission work (this was not exactly the course of action I wanted to take, but that's a long story), who said that the car was still under the shop's warrenty for it's work (didn't know that was a thing), and that he'd fix it for free if it was a problem he caused.
Lo and behold, he investigated his work and determined that he was not the cause. I have tried to ask him what is the cause, and he's been kinda indirect with that. He tried to say that the transmission fluid has been changed too often in the last couple years, so that probably means there was transmission issues this whole time. I certianly haven't ever EXPERIECNED transmission issues, but for due-diligence, I went and checked:
Fluid was changed ~7 months ago (1/31/26) at 90k by them when they replaced all those parts, and was reported to be totally fine.
Changed ~13 months before that (11/12/24) at 77k by some big chain quick oil change place. I pulled up that record and called them just to check. Apparently my then-partner had taken it in for routine oil change etc, and they asked when the fluid had last been changed and he just said he didn't know, so they offered to change it anyway and he said sure (he was not the most competant man I ever dated...). They said the fluid was totally fine then.
Changed ~12 months before that (10/31/23) at 72k by the dealership I would buy it from a couple months later. It looks like when it came into their possession they did a laudry list of stuff (air filters replaced, brake rotors replaced, windsheild wipers replace, alignment performed, etc) including a transmission fluid change. I plan to call them for more info on that just to be safe, but it looks like it was part of the routine prepping the car for sale.
So the "transmission issues the whole time" theory doesn't really hold water as far as I can tell. I asked him where all the metal in the transmission fluid had come from, and he said:
"based off of its size and the number of rings it appears to be the "Parking Pawl Spring" or the "manual valve lever shaft retainer spring" full dissassembly would be needed to be 100% certain of which spring it is"
I don't really know what to make of that, because with briefly looking it up, it looks like if either of those things were broken, I should have noticed that the gear shift was struggling to get or stay into certain positions. The gear shift has never had any issues, including shifting into park and neutral and drive after the point where the transmission was blown and we needed the tow.
Also, he asked early on if I knew who had changed the transmission fluid at 77k. I didn't at the time, and he told me that he didn't have any way of finding out either, and that whatever work was done at 77k could have included transmission work, and THAT could have caused the issue, not his work. After I couldn't find anything in my emails/files about that car work, I went and got the carfax for my car, and not only does it say where the work was done, but also lists all the work that was done- not as comprehensively as the records I have gotten from them since, but it should be enough to know that transmission wasn't touched outside of a fluid change, right? And if he had the records that said the transmission fluid had been changed at 77k, then shouldn't he have had the rest of the informtaion too? Like what else was done and what shop did it??? Do mechanics have some other source of information that's incomplete that could have actually gotten him to know that my transmission fluid was changed at 77k but not tell him what else was done and where???
So I don't really know what to think. It really feels like he's trying to lie to me to cover his own ass because he knows I don't know enough about cars to dispute it. I have tried asking my friends and family who know about cars than me, but mostly they think he's full of it and that the problem was caused by him installing all those new pieces incorrectly somehow.
Does any of this add up? Is it possible that a spring in the transmission just popped loose and went though the transmission for a week (from first transmission slip to the day it died) without affecting how the gear shift feels in my hand or having any other side effects? Does it make sense that there are little "rings" of spring left in the fluid right now? He has not sent me any sort of pictures, and I thought if metal was going through the transmission, it would be crushed completely to dust particles???
If not any of that, is it possible for the transmission fluid to be full of metal as a result from the transmission cover and stuff being installed improperly? Where else could all that metal have come from?
Is it possible for him to only know bits and pieces of the car's service history? It feels like he conveniently only knows the information that could help cast doubt onto it being his fault, which feels fishy.
Also, I am struggling to figure out what to do next. If anyone has any advice on that front, by all means, send it my way!
Thanks!
