Hi i have a 2003 acura tl having transmission issues.the car would run once it warmed up it the transmission would start slipping and then eventually not move at all in any gears no reverse or drive but if it cooled down it would go into gear again. Well i pulled the transmission and took it down to get it rebuild and i reinstalled it and started it up and it went into gear fine well drove it and same thing warmed up and no gears but if i put it in park and cycle the key and start it up again it will go again into gear but if i stop or drop below 20 no gears untill i cycle the key then i can go again but it slips well today started it up and now nothing no reverse or drive but sometimes it will take a little while to go into reverse or drive sometimes it wont..very puzzled

Welcome Boisetunner

First is the check engine light on? D5 light on the dash blinking ? Is the ATF level ok should be between the dots if done right.
Inspect all the connectors on the transmission
Make sure the ground cables are installed correctly.
The range sensor needs to be in the correct position when installed.
Scan it for codes it may give some clues.
Lastly look under the car for leaks.

If all of the above checks out ok then the rebuild is in question.

boisetunner

There is no check engine light on and the D5 light is not blinking but it is on when i turn the key on but shuts off with the maintnance light turns off also all the connections are correct and snug and all grounds in the correct locations and no leaks the rebuild is good they have rebuilt an odyssey and a accord transmissions for me before pretty much the same tranny and were all fine the funny thing is it is doing the same thing as before before it was rebuilt.

Were the old solenoids reused ? If so that can be the problem.

boisetunner

when it goes into gear it runs good no slipping or nothing shifts ok but once you slow down under 20mph or stop nothing just sits there wont move give it gas rpms go up acts like its in neutral but if i put it in park and turn it off and wait 5seconds and start it up and put it in gear about a 2 second pause then it engages and goes again

boisetunner

I believe they were used but not sure which one to replace they are pricy little boogers the lower solenoid B single linear solenoid alone is 285.00 and the ttc solenoid is 105.00 thats only 2 of them lol so not sure where to start

ErickUa5

The rebuilder is supposed to be able to test them, they are pricey so make sure before buying any.

Did the tranny rebuilder find anything really bad within the tranny when tearing it down ? If things didn't appear too bad, the real problem may have been what you're now experiencing.

Check all the external stuff as previously mentioned. if there's any CEL codes, that should help isolate the problem. How dirty was the old fluid before the rebuild ? Hopefully it's something that was simply overlooked.

Ok update i took the transmission back out and took it back to the rebuild guy tore it open and one of the main pressure seals inside had tore replaced it and installed it back in ran awsome shifted fine drove it for 44miles and once again started acting up again started to slip again check engine light came on p0730 incorrest gear racio and p0740 torque convertor lock up solenoid so i replaced torque solenoid and the a/t pressure control valve C and pressure control valve A/B solenoid and nope didnt fix it im lost

boisetunner

Also i was there for the tear down of it and it all was fine no clutch pack damage no burnt fluid just puzzled could it maybe be the torque convertor

I think your dumping to much on the transmission. The rebuild shop should have everything ready when you picked up the car. You should be driving without issue right now. Are these guys friends or family?

Ok so this is how it starts;;;;;Hi i have a 2003 acura tl having transmission issues.the car would run once it warmed up the transmission would start slipping and then eventually not move at all in any gears no reverse or drive but if it cooled down it would go into gear again.

Did you replace the transmission external oil filter. It could be clogged. This is the first thing to look at that caused the transmission to fail.

boisetunner

Ya it was replaced

fsttyms1

Was the Tq converter replaced? Were all the solenoids replaced?

boisetunner

torque convertor was not replaced only solenoids replaced were the ones i mentioned he used to work for ammcco transmission and went on his own and has been rebuilding transmissions for over 25yrs i have took him many transmissions to rebuild including accord and honda odessey transmissions and never ran into an issue like this one just puzzled

03blackbeast

My car has had the exact same symptoms for a while. Haven't gotten around to fixing it yet because of lack of funds. Are you getting any weird noises? Mine has a weird electrical whine towards the back of the tranny near the engine block. I'm interested to know what the outcome is here since I may be looking at the exact same problem.

boisetunner

you know this was doing the same winny noise and it went away after replacing the seal that tore it is inside the transmission on the first clutch pack that goes into the main pump unit

boisetunner

it is the secondary shaft sub-assymbly is were the seal is located that was making the winny sound he replaced it and it went away it was letting the trans fluid escape through it causeing low trans oil pressure

boisetunner

I am running to grab a torque convertor for this thing today 136.00 my cost and throw it in and see if that cures the problem fingers crossed cause i dont know what else it could be unless its the hydrolic system for that i have a good scrap tranni that came out of a tl that was wrecked in the front and made a half dollar hole in the tranni center housing

ErickUa5

After many years people develop shortcuts.
Most Honda transmissions are sealed units, Make one mistake and your back to square one.
This transmission needs to be brought back out.
The valve body needs to be updated and checked thoroughly, lastly the bolts need to be torqued down to spec or seizure will occur within the valve body.

boisetunner

the transmission takes only an hour if that to pull it not big deal done it plenty of times and all the internal parts were replaced and upgraded and torqued to spec. the guy that rebuilds my transmissions that has over 25yrs experience doing it has never had a problem with the transmissions i take him and he has done more than 6 odyssey and accord transmissions last year for me alone pretty much the same transmission and those turned out fine but guess there is a first for everything but its a honda what you expect poorly made transmission nice cars but poor quality transmissions. plus i have some room to play with cause im only 550 into it total.alot cheaper than 2500-4500

03blackbeast

Was this also causing the code P0730 you were getting? Because if so you may have just solved my problem. Although, I'm getting the exact same gearing issues you are. It'll work and then just stop after a while. What a tranny

boisetunner

nope still has the p0730 code and the p0740 code going to throw a torque convertor in it tommorow see if that fixes it torque convertor solenoid been replaced already and i can get a new torque convertor for 139.00 my cost we shall see

boisetunner

quick question will a 2002 honda accord or a 2002 honda odyssey fit a 2003 acura tl and wwhat has to be swapped over

3.2TLc

While I may be wrong....the '02 Honda AT is still the old design and not worth the effort even if it did fit. Why risk problems to save a few bucks ?

Go for the newer improved and much more durable '06>'07 Honda AV6. Do it once and do it right !!!

Memphlow

This is the second thread today where people have experienced transmission problems after rebuilding and or swaps where the original torque converter was used. This may be worth noting when addressing problems with our transmissions. I am going to post this reply in that thread as well. Is there a way to inspect the converters

ErickUa5

That I know of if its discolored blueish means its been overheated and no good, but still original converters are never to be reused on a rebuild.

3.2TLc

Yeah, better safe than sorry later......if in doubt, do the job right !!!

I recently came across this issue too on my 2001 TL. Winny sounds from the bottom of the car (where the torque converter is located inside) have to restart the car to let the gears to grip. I already checked Lock-Up Solenoid, Shift Control Solenoid Valve A, B, C click test and all are working perfectly but still having the shifting issue, mine occurs after warm up too, first and second gears goes smooth but when it comes to third gear is slips but then catches up on fourth and fifth. (so puzzling) I will check the A/T Clutch Pressure Control Solenoid Valve A/B Assembly and the A/T Lock-Up Clutch Pressure Control Solenoid Valve. I'm attaching a PDF file that I came across online when I started my research. Hopefully someone came up with a conclusion to resolve this issue.

Yoshimatics, have you tried a drain and fill with Honda ATF ?
Sounds to me like a clogged internal filter and not much you can do about it but replace it with the AV6 trans.

Yoshimatics

I haven't done that yet. Did you had the same issue with your TL??

amgates80

ever figure out what was wrong?
