Transmissions look so complicated. I guess thats why they pay you the big bucks! I had to P1811 code. took the side plate off, and changed out the pressure control solenoid amongs the shift solenoids, and a shift kit for good measures. Ive read that it could be many things that might of gone wrong. Worn clutches, worn accumulators, valve body..even the MAP sensor. If I missed anything please add to my list. I hope I caught it time becuz after I did the repair No code. I dont really drive my Buick much. Its more like my project car. Take it out for drives from time to time. thank you for the great videos.

Hi Gary. Played with the scan tool today on my Lesabre got the following results: 1-2 shift time:.28 sec. 2-3 shift time: .35 sec. 3-4 shift time: .30 sec. The 1-2 tap cells were: 4:21.76, 5:23.01, 6:18.25, 7:17.25, 8:11.75, 9:14.75, 10:14.75. The 2-3 tap cells: 4:12.5, 5:20.01, 6:19.26, 7:20.01, 8:15.00, 9:15.75, 10:15.75.

[@GaryFerraro]

To Michael D, I have no idea what happened to your comments, I can't find them. The reason why it was shifting hard on the 1-2 shift is because the computer was adding 30psi of pressure to make up for the slip it had from the worn 2nd clutch pack, these clutch packs come loose from the factory and when they wear out get way to much clearance.

[@GaryFerraro]

Once heated it shifts harder and just stop all together shifting in any gears until I let it sit for a while then it’s back driving.

1811 usually worn clutch packs in 2nd and 3rd. P0742 code can be tricky, a lot can cause this code to show up, this is internal to the trans as well. Don't think the engine will cause this but i would change it and get that fixed

If the car only has first, the 2nd clutch may be bad(2nd clutch is on in 2nd,3rd,and 4th.

[@GaryFerraro]

+Adrain Branch I honestly think it wont affect anything. One of the main reasons why i tighten up the 2nd clutch alittle is beacuse if the person is heavy on the gas pedal and the clutch pack clearance is on the high end but within range it may flag the 1811 code. Becareful of what you get, smart to take yours out first, count the sprockets and the final drive, also make sure the pitch of the gear is the same on the final drive as well.

[@GaryFerraro]

Speed sensor in the channel plate and solenoid in the valvebody, can get to both by removing the side cover

[@MrVincinzo]

Can u test the solenoids with unit intact and first to determine if solenoids r bad and is it more likely with the 1811 error code means parts of gear box more likely worn?...if solenoid shows up first, better to replace solenoid or have trans rebuilt?...

[@GaryFerraro]

MrBiGHacC The 1811 code means something is worn out, most of the time its because the clutch packs are worn, other reasons for the 1811 code are a internally worn EPC Solenoid or a worn boost valve. To answer the question about checking the solenoids with the unit intact, the only thing you can do is ohm them at the case connector, but if you have an internally worn out epc solenoid it still may ohm ok. If a solenoid code shows up, it really depends on what code it is to determin what direction to go, you have eletrically generated solenoid codes and you have solenoid performance codes. A solenoid performance code is more hydraulically generated if the computer sees a wrong ratio for the gear commanded. An eletrically generated code is solenoid, wire or computer. As far as the 1811 goes, i had one case with a bad epc solenoid, all others trans just worn, never had a boost valve and sleeve issue. Gary

If i do not remove that snap ring, can the chains still be removed? I want to do the work in the drivers side wheel well with the cover removed. (For a Venture)

[@GaryFerraro]

Not a snap ring, its an o-ring, ive never tried it but it may be do-able. You may not be able to get the drive sprocket out do to the o-ring, but it may be loose enough to remove the chains. Gary

[@GaryFerraro]

Hello, This code could be a few different things. First, its shifting hard because to defaulting to max line pressure. Causes for this code. Tcc solenoidvalvebody issues, such a worn out valvetrainsTcc release switch stuckProblems in transmission channel plate. and more...usually the trans has to come out to be overhauled. Are you in the new york area?

[@GaryFerraro]

how did you make out with your trans?

[@GaryFerraro]

So now you have the 742 code? if so i can e-mail you some info on that.

[@GaryFerraro]

Sure, my e-mail is [e-mail], you can e-mail me your address.

Good morning my name is Bernard I live in homestead Florida and I just watched your video on 4t65e transmission teardown.. my question is a 2002 Pontiac Grand Prix GTP and I take a transmission out of a 2005 Impala SS and put it in my 2002 Pontiac Grand Prix and now I'm getting a p1810 code when the transmission won't shift and I know for a fact that the transmission that was in the Impala SS didn't have any issues whatsoever because I drove it myself it was my car any ideas I still have the computer from the Impala SS

[@GaryFerraro]

In 2003 some of the electronic solenoids changed, there are also 3 or 4 different internal harnesses.

[@chanceoc84]

it just won't shift into gear is there anything I can do?

[@GaryFerraro]

Its probably in failsafe mode, if you clear the code what happens? Also, there are different sprocket ratios which also will throw codes but not the one your getting.

[@chanceoc84]

Gary Ferraro when I clear the code it does the same thing and on top of that if I drive it early in the morning when I wake up I think it shifts fine but after it warms up it won't shift the faster I go to higher RPMs go

Nice video Gary my girfriend 02 Buick century is shifting hard when is hot shift smooth when is cold i hear can be the EPC SELENOID sorry for my ignorance but how i can pull codes from the transmission? is so weird the car have 133,000 and oil was change it on time

[@GaryFerraro]

+Melvin Santiago Fisrt thing to do is to get the car scanned for codes, to see if any are present. You will need a good scanner like a snap-on scanner. If there are codes, that could be the reason for the hard shifts. The code will give some direction on what to do. Gary

[@abelruiz4524]

at 27:50 mine is leaking from there! is it ok if i take the cover out and replace gasket???? trans still in car

[@GaryFerraro]

+Abel Ruiz Just to confirm, have you cleaned it down and saw the leak coming from the cover, only reason why i ask is because its not common for it to leak there, the bolts are tight? By the way there is an o-ring that seals that cover

[@ohwell4789]

+Gary Ferraro yes i use a wire brush to clean the area! start the car let it run for 20 minutes i look again and it is leaking from that cover, and i wonder if its safe to remove it an get a new seal. Thanks!!!!!

[@GaryFerraro]

Ramirez Ruiz If you remove it, you wont lose the band, it will stay in place, just may be a pain getting the cover off.

Hi, sir, we have the problem with 2006 Toyota Sienna . When we start driving it shift OK but drive at high way about 20 minutes it`s no shifting at all. We have already changed valve body three times. It has same problem. What would be the problem ,sir?

[@GaryFerraro]

Saw Tun does the car stop moving or stop shifting? Does it go into failsafe? Any codes present ?

[@sawtun3294]

Car stop moving and shifting.sir.

[@GaryFerraro]

Ok, Sounds like the filter is clogging up, as a test, when this happens and the car stops moving, shut the car off for about 2 or 3 minutes, start it up again and see if it can move,( you may be able to drive a few blocks).

[@sawtun3294]

No code,sir . The car stop shifting and no moving but engine running.We asked somebody they said valve body issue. We hanged valve body but same problem

[@IDK_Mr.M]

I have no codes and low pressure almost to the point the car will not go forward unless on jack stands.but I have good reverse.

[@GaryFerraro]

sounds like a broken band, if you have good reverse, pressure is probably ok.

Hello, I have had the p1811 code before even tho it has disappeared. Whenever I drive more than 20-30 miles, the transmission completely stalls. After sitting for a while (30 min), I'm able to start the car in Neutral and I'm only able to drive home using the 1 and 2 gears on the selector. Shifting into Drive and 3rd usually stalls the car. I have 97,000 miles. Help please?

Do you have a video of doing a 4T60?

[@GaryFerraro]

I do not sorry, i see that transmission every once in a while Do you have a problem with one?

[@widtrak77]

Gary Ferraro I have a 1989 Regal GS I have owned for 23 years 246k on the original transmission! Always serviced but now when its cold it does not shift out of first gear unless I warm it up for a while. Once it finally shifts it shifts normally after that. I'm sure it's ready for a rebuild but what do you think is causing that a hardened seal?

[@GaryFerraro]

Very well could be a hard seal, it may be in the 2nd clutch, the 2nd clutch is the driving clutch, that means without 2nd you will not have 3rd or 4th. Can't remember the last one i had in the shop

[@widtrak77]

[@GaryFerraro]

+James Abbott What year car do you have? Gary

[@jamesabbott8968]

04 impala

[@GaryFerraro]

+James Abbott It really boils down to a few things, either there is too much clearance in the clutch packs, this would make the shift long and drawn out at higher throttle openings, how to you drive, do you tend to get on the gas? the other problem could possibly be a bad epc solenoid. How does the car shift? Gary

[@GaryFerraro]

If the only code is the 1811, that usually indicates worn out clutch packs. If you know someone with a snap-on scan tool, look at the T.A.P(transmission adaptive pressure)cells, the computr is probably adding pressure to kep th trans from slipping and at a certain point it can no longer add and flags the code 1811
