Just when i thought it was all fine and the transmission was done getting rebuilt, A week later it had an episode.

I was driving at around 40 when i got a TCS CEL and flashing D5 come on out of nowhere. I had to stop at a stop sign and first gear acceleration was horrible. It would be up to about 3000 rpm and be going 10mph. Extremely weak feeling until it would shift into second. From second gear up it shifts perfectly like a freshly rebuilt tranny should.

Before i go back to the shop to get this fixed, what should i be expecting here. What could have this guy done wrong!!!

I have had it with this transmission Problems ( Sorry have to let some steam out)

Hey Mcottrell, have the CEL codes read.....might help to determine the tranny problem, just maybe !!! It appears as though the car has defaulted into limp mode by the way you had described the situation.

Too bad ya didn't have an '06>'07 Accord V6 donor tranny installed rather then rebuilding the "POS" original tranny. But hey, live and learn !

For now, just take it back to the shop where it was rebuilt......as only they might know what went wrong during the process. Could be as simple as a solenoid, IDK.....sorry for your luck.

Hopefully they filled it with the Honda/Acura DW-1 fluid.

Its in limp mode (safe mode) The ecu has detected a fault. Hook up a scanner and it will show a code, write it down for the rebuilder so they can have an idea of what they're doing wrong.

mcottrell95

As soon as i get my reader later ill post the codes. Fluid looks too red to be honda fluid. You may me right about that

victus1

Honda & Acura transmissions are very picky about their fluid and will fail sooner rather than later on the wrong fluid. This is documented in their service manual.

When you talk them....don't mention anything about DW-1. Just ask them exactly which fluid they used.....the generic one they have on their shelf? If so, then you can shit on them!

It may or may not be what caused your problem, but regardless....they should only use the Honda/Acura brand.

P0780 is the code.

If i understand correctly that has to due with the solenoid valve? What kind of repair am i looking at here?

Im probably going to replace the fluid myself just to be on the safe side

ErickUa5

It might be as simple as pushing in a connector on the solenoids or a broken wire. Inspect the wires and connectors.
If when you pull on one and just pops off without pressing on the tab that could be the one.

3.2TLc

The code P0780 indicates a possible mechanical problem within the hydraulic control system.

It could be a faulty shift control valve "A", clutch pressure control solenoid valves "A & B" or perhaps a problem with the PCM.

mcottrell95

I was just told that when the tranny was rebuilt that he knew the solenoid was going,but didnt think it would go this fast. As soon as he heard p0780 he wasnt too happy with himself. Hopefully this will solve it just with a 200$ part

As always you guys are a great help and i apreciate all the good ideas and advice.!!

3.2TLc

Can't understand why someone would do such a thing.
$200 part vs: $2000 rebuild ???
Bummer.

Memphlow

This!!!! I would be leery of anyone who would take such a risk. I would have too pride in my workmanship, my reputation, and my customers time and money.

Before my tranny went it came up with the p0740 code and I replaced the solenoid with what I believe is the same part. 200.00 later the tranny still failed.


Maybe what the transmission guy is telling you will do the trick hopefully.

3.2TLc

Maybe, but maybe not !
Could be that something else was also overlooked or not thoroughly done at the time of rebuilding the tranny.
Ya never really know when some of these shady guys are blowing ya off !

ErickUa5

If its not electrical or solenoid problem then he's gonna have to bring the tranny back out, but rest assured he's gotta do it right this time. Then you can take the chance to change out the rear main seal and mounts unless it was all done already.
If I remember you were having an issue when you took it out the shop right?

mcottrell95

Well i work for the dealer that owns the shop, i know that it isn't the best workman ship, but I'm only paying for parts luckily. Its already been out twice, however the shifts are absolutely perfect.

It gets aggravating that i need to keep losing the car for a week to get it redone, but who am i to complain?

Its all about the situation, unfortunately there were a lot of corners cut the first two times :/

Yikes

P0740 is different. Most times when you get a P0740, the damage is already done and that code pops up because the solenoid isn't getting the proper amount of fluid due to a clogged screen.

I could be wrong, but that's how I understand it to be.

3.2TLc

The code P0740 indicates a problem within the lock-up control system.

It could possibly be a faulty lock-up control valve or lock-up clutch pressure solenoid valve. Often caused by a badly worn torque converter.

Nicks2001tl

Even with the code P0780 and the new solenoid that is to be replaced the solenoid might not do the trick, and 200.00 gets wasted on false fix. I`m a little skeptical when it comes to fixes on these trannys.

3.2TLc

The original trannys are doomed from the git go, no doubt or skepticism about it.
But by now, ten plus years later...most of the bad trannys have been replaced or rebuilt a few times.

It's a long shot.....however very possible that if the fluid wasn't properly maintained, that the solenoid valve screens could become restricted and cause problems with shifting. So, inspecting....cleaning....replacing may be worth the effort, IMO. $200 vs: $2000....ya never know for sure !!!

Mcottrell95, Ask the rebuilder if he uses Sonnax parts for the valve body, it eliminates the design flaws in which they claim that you wont need the oil jet after the parts are installed because it increases cooler flow. Theres a guy on Youtube that explains how these trans work and also mentions that he's had success with using the updated parts.

mcottrell95

He used oem already on that before. I wish i woiuld have known that before ithe rebuild:/

Fortunatly it seems like the tranny is doing very well now even without the linear solenoid installed yet. Thats why im pretty confident that its just an occasional issue where the valve sticks and causes the malfunction. Once the roads are better im going int to get it changed
