SOURCE: tcc solenoid code

This is a transmission issue, TCC is Torque Converter Control, the solenoid is inside the trans, unless you are a well versed technician I would leave this to the transmission experts, you might try premium assistance for someone that can provide more detailed step by step repair procedures if you are determined to do the repair yourself.

Cylinder number 5 is misfiring. Check spark plug, spark plug wire and ignition coil for the number 5 cylinder. The number 5 cylinder is the closest to the front of the car on the drivers side. With engine running in dark (at night) take a spray bottle of water and lightly mist spark plug wires and coil and look for arcing. Autozone will test coil for free.

Repairing a converter clutch solonoid circuit stuck on

The TCC solenoid is inside the transmission.. It is controlled by the computer .. which takes singles from the heat sensor, the speed sensor, the brake sensor. Its job is to increase fuel mileage by reducing slipping in the converter.. You need to check the wiring plug at the trans and see if it has a single from the computer keeping the TCC engaged... OR is it a mechanical problem with the solenoid.. Then you can trace which circuit is causing this OR if the solenoid is defective.. Hope for the solenoid.Post a comment and let us know what you find..

94 buick park ave runs great but with a light load it shakes, accelerates good and in park or neutral is smooth changed plugs and wires

Several possibilities having to do with the torque converter clutch and TCC solenoid:

1. Replace transmission fluid, use a synthetic Dex VI, do a complete flush with pan removal and filter replacement

2. Check all grounds related to the transmission control solenoids, clean them and ensure good electrical contact.

3. Rebuild transmission, the TCC friction material is worn out.

2004 buick regal code P1887 (TCC switch) Where is the TCC switch

Code P1887, as you probably by now know, is set when there is an issue with the torque converter clutch engagement and disengagement. When this code is set, it inhibits TCC operation, could cause issues with the shift adaptive strategies and possibly issues with 4th gear (Overdrive) operation.

The unfortunate news is that you have the 4T65E transmission in this vehicle and the TCC switch/solenoid is part of the valve body and the valve body is on the side of the transmission (drivers side) and would require at least the lowering of the sub frame to get enough clearance to remove the side cover and to get to the valve body. It is really an involved repair and would not be for the faint of heart nor those with little to no mechanical experience.

I dont know where you are located, but if you are anywhere near Indiana I would visit and sign up there and post up your issue there. Its an online community for Grand Prix's and other vehicles that use the GM 3800 engine. There is a gentleman on there that goes by the screen name of Trannyman95 and he makes his living rebuilding 4T65E's among others and is highly regarded as a top notch transmission builder.

1999 Buick Regal hesitation while driving

most likely it is not actually a misfire it is the overdrive/TCC solenoid kicking on and off, it is a common GM transmission issue
