ECM hard shift

My toyota was doing the harsh shift issue, took out the ECM and had it rebuilt, the guy said it was too far gone, he has to send me a different rebuilt one, so now I have sent him $450 total. Took it to Toyota and had them 'flash' the ECM, they said it was driving awesome, tried to drive it home and it is worse than before, took back to Toyota and they said it could be a bad ECM OR my Transmission.....can't believe they don't know which one it is. They want me to buy a new ECM from them for $1000 and if that doesn't work, then buy a transmission. I don't kow what to do

This is a known condition. And, is under warranty.

Take your vehicle to a Toyota dealership. Ask them to replace your ECU per TSB (Technical Service Bulletin) TC015-07. The new ECU has redesigned logic that rectifys your condition.

Not likely to be the clutch pack as you dont mention slipping wich is the normal sign of overheated or worn clutch bands.Not sure with your vehicle but 2 methods that control the shift severity are engine vacuum or pump pressure inside the auto. so check balls are a possibility. They are spring loaded to open at a set pressure,or close.Could you check to see if its a vacuum controled and if so its a lot easier to fix as the vacuum control should be outside the trans.

The ECM (or, Electronic Control Module) is covered by the factory warranty for 96 months, or 80,000 miles, whichever comes first. Have your dealer refer to Toyota technical service bulletin "TC002-06" for info proving this. The fix is to replace the ECM. If you are below the above parameters, the repair should be free.

Also, if you have ever had your transmission fluids changed, it is CRITICAL that you use a specific auto transmission fluid, Toyota type "T-IV". Any other fluid will cause you problems. Please feel free to respond if you have any other questions; and Thnaks for choosing FixYa!

I don't know where you got the price quote,but a new one will be $3700 (Then you will need to pay an additional $350 for installation)

A rebuilt is $3300 (Not including removal and reinstallation)

A used one if you can find one will run about $1750 (then you will need to pay an additional $350 for installation)

You can check new,used and rebuilt price here
Give me you state and zip and I will find a local shop that can do it.

2005-07Toyota Corolla Hard to Start/Harsh Shift/Check Engine Light On


There is a known issue with the 2005-2007 Corolla automatic transmission shift logic. The shift points may seem harsh, and the Check Engine light may be illuminated.

There is a technical service bulletin published that will address and rectify this condition.

The diagnostic code P2716 will be stored in the computer memory. The procedure involves replacing the Engine Control Module (the computer) with an updated unit.

The repair is covered, under the factory warranty, for 96 months, or 80,000 miles, which ever comes first.

I hope that this helps Corolla owners out.

Regards,

Does P0741 mean a real transmission issue and/or ECM problem?


Just take car to AutoZone to use their Diagnostic Code Reader and then they can look it up and tell you what is wrong and part that you should replace.

Where is the valve body on toyota rav4 2003 located


I would need visuals of the valve body, and for that year rav4 they are getting over on you with the price of the transmission.
The ECM replacment would have been the first thing I would have done, as the the ECM controls all the valve servos in the valve body.

most of the time it's not the body that goes bad but the servos or the wiring. But in your case, 99.9% positive your ECM shift control programming has gone bad.

I have a 1989 bronco XLT 4x4 with a 351w auto trans. I just bought this vehicle 2 days ago. The guy i bought it from had the ****** rebuilt, but its not under warrenty anymore. My transmition shifts...


The transmission builder could have done some shift improvement to make it do that. Shift/rebuild kits can have different levels, stock, street and strip or hauling for instance.

Lexus rx300 2002 hard shift between 1st and 2nd. Fluid and filter changed 3000mi ago, car has 93000mi


The 1999-2003 Lexus RX300 models have a common failure of the engine computer that causes the harsh shifting of the transmission. You need to get the computer (ECM - Engine Control Module) rebuilt or replaced before it causes permanent damage to the transmission. Even if the transmission is already ruined, the ECM will still need to be repaired. Most often, the transmission is fine though, and rebuilding the ECM will restore the smooth shifts that the Lexus should have. Circuit Board Medics can rebuild the ECM and reprogram it so that you only have to plug it back in when you get it back. See the link below:

Harsh or improper 1-2 upshift


Have you had your throttle position sensor checked out? It'll cause a harsh and/or delayed shift from first to second. Second thing to check out is your PCM, as it controls the shifting of your transmission.

Shifting hard


You probably have a DTC code of P-2716.

Toyota knows about this issue, and a new engine Control Module (ECM) has been developed to rectify this condition. If your car is under 96 months old, and has less than 80,000 miles, the ECM will be replaced FREE by your Toyota dealer. The replacement ECM corrects the shifting issue.
Mention Tech Service Bulletin "TC015-07" when you take it in for service. If you are beyond the time and mileage as listed above, I can give you the part number for the ECU, if you want to purchase one.

2005 Toyota Transmission downshifts rough


Sounds like you need the updated engine computer for harsh shifting. Look up under the glove box at the computer. Number should be 89661-02K21 if not, you need the update. It is an 8/80 warranty item.
