As some of you might know, about a month ago the transmission in my TL failed. (Big surprise, I know :silly: )
However, as it turns out the code it’s throwing is P0750. After doing some googling, I’ve learned that it’s related to shift solenoid A.
I know these cars, as well as Accords and Odysseys (among others) from this vintage are synonymous with automatic transmission failure. However P0750 isn’t (as far as I’ve seen after years of researching this topic) one of the more common transmission failure codes like P0730, P0740, or P1750.
I’m going out on a limb here and asking for anyone with extensive experience with these types of failures (tech, trans rebuilder, guru, ect) to tell me how common P0750 is on in regards to run-of-the-mill Honda A/T failure. I figure that the solenoid is just clogged up with clutch material, which means that the transmission has indeed failed, and it just happened to clog that solenoid before other problems cropped up.
Because I’m an unemployed college student, I’m left with either junking the car or selling it for a few hundred dollars since I can’t afford to put a transmission in it right now. So if there is that rare chance that it’s simply a bad solenoid, I’m willing to take it. Is it worth the time of putting a new solenoid into it? I know I’ve asked for people with previous experience to answer, but I welcome all responses, as anything is appreciated here. For anyone who is interested to know, it has the updated, post 2005, casing redesign. (This was supposed to help curb failure rates and increase flow of ATF, but even these updated case designs aren’t immune to the common failure, it seems.) Thanks.

My car is not a honda… but the 4T65E is also know for its issues, and solenoid issues is one of them let me tell you, sometimes its the valve body itself is junk and the valves stick, sometimes its because a bunch of clutch material gets stuck in the valves and they start to stick, but most of the time the only fix to the issue is pulling the entire transmission, and at the miles this typically happens it would be better off all together to just re building the transmission if you are going to go in that deep.
And if a honda is anything like that i wouldn’t just replace a solenoid to tear out the entire trans, i would get the trans overhauled or what ever you do when they go out, get it done… get it over with.
Thanks for the reply.
As far as my research tells me, it’s rare that the shift solenoids fail (not talking about the pressure switches here). Their ability to operate is usually hindered by clutch material or other debris clogging them. As far as actuation failure… that usually isn’t the case.
I agree with your statement, however. It would be easier to just put a remanufactured transmission in it and be done with it. However rebuilt and remanufactured units still have the same design flaw that caused them to fail in the first place, so at best it would be a temporary band-aid until I can afford something else.
I got a call from one of the dealer techs today. They want to buy it for $400. My loss, his gain- everything about the car is in great shape considering it’s 15 years old and has nearly 220,000 miles. S*** happens, right?
Seeming as this is a pattern failure, I really wish Honda would have helped me out here, but I completely understand why they decided not to. (The car has been out of warranty for over half a decade!) I’ll be graduating with my mechanical engineering degree within the next year, and I’ll be buying plenty of new cars over my life time (hopefully.) This could have been a good investment opportunity for them to make me a lifetime customer. I’ll remember this experience when buying my first new car. What a shame.
I have extensive experience with those cars and those transmissions. In fact, for a time I was installing up to 2 of them a day for more than 3 years. That should tell you something. In my opinion, that’s the worst car Honda ever made and is an embarrassment to the brand. The transmission is only one of it’s many issues.
To answer your question, it could be a solenoid issue, I have seen that on occasion, but with the frequency of failure of those transmissions, it may not be long before you have to address a mechanical failure within the unit. Between that, and the other numerous issues with that vehicle, I would recommend finding a different vehicle. I’d see if I could get more than $400 for the car though. If the tech really wants it, he’ll pay a bit more. I’d ask for at least $600.

Good luck and please keep us updated on your situation.
Update:
We settled on $500 for the price. I originally asked for $700, but truth be told I just didn’t want to deal with this anymore. I didn’t want to fiddle around with cleaning or replacing solenoids, but the fact that the transmissions works fine for about 15 minutes tells me that the transmission is toast because the clutch material settled- only to be stirred back up after a few minutes of operation.
I got into a 1999 Jeep Grand Cherokee with the 4.0 I6 (It has it’s own host of problems). I’m sure you’ll see more threads crop up about it in the near future.
Thanks for the replies and advice.
