Question about Pontiac Bonneville

Open Question

I have a 1999 Pontiac Bonneville, 4T65E transaxle. It has a 3.8L K engine, and 206,000 miles on it. The Transmission only has 1st and second gears, will not shift into 3rd-4th. and P0756. It also had a loud whine like a bas power steering pump at idle and it changes with engine speed. I removed the trans and tore it down, I found a stripped 4th gear clutch hub and shaft/and sun gear. I used to be a GM tech, but since i work for a Ford Dealership. I rebuilt these units before but long ago. Whati need to know is, with 200K on it what would you reccomend replaceing (other than the obvious) while i have it out and apart to stave off the "known issues" I have already gotten a new PCS, 1-2 and 3-4 shift sols. The fluid was old but not burnt, and without my Service info i cant see if the 4th hub/clutch would cause a no shift from 2nd. Thanks Rick

    I found the issue It was the OD stub shaft. splines were stripped. and it was limited it to 1-2 only. I took it out and overhauled the trans, and installed a new shaft. Thanks

SOURCE: transmission won't shift to 2nd and 3rd gears goes from 1st to 4th.

Doesn't sound like a simple fix. I would suggest having it serviced.

Sounds like a bad countershaft bearing. The trans will need removed and disassembled to fix it.

SOURCE: My 1994 Ford Explorer automatic transmission won't

Hi there,

As your Auto transmission is fully electronic, it could be anything from faulty sensors sending incorrect signals to the trans computer, or faulty internal components. Your best bet is to have the trans computer scanned for 'fault codes' (as the computer monitors and retains all faults) by your local Ford dealership.

This process will identify the likely component/s which are causing this problem.

My guess is, there may be a problem with the 2nd clutch (yes that's right, automatics have internal clutches!), input and/or output shaft switches sending incorrect signals to the computer.

But, there could be so many other possibilities....so, I recommend you get the codes scanned and go from there.....

If the whine is there than the main bearing is already worn adding fluid will not save it, you will have to swap it or rebuild it. sorry i know you were hoping for something better.

Can you put a transmission from a 2002 chevy impala in a 1999 Saturn sw2


about replacing a transmission with one from a Junkyard or cross referencing them. and to show you that not all 4T65E transmissions are interchangeable, although they look alike. Guys with the comp g package or the Impala police option often find this out the hard way.
Your car and the potential donor car will have a tag in the trunk (usually under the spare tire cover) that lists the RPO codes for your car, along with your VIN. RPO=Regular Production Order. Several of these codes relate to the transmission, and you will need them to begin to find a proper match. If you can't find the RPO tags, you can look up the RPOs for a nominal fee ($5) according to the VIN number at the following website: www . compnine . com .
I know these transmissions are different in at least 5 areas, and you have to match each area for a proper swap.
FIRST is the transmission type, which relates to torque converter size, the strength of the internal gears, and the strength of the differential. Here are the basic types along with their RPO codes:
M15 - 245 mm (9.6 in) torque converter
MN3 - 258 mm (10.2 in) torque converter
MN7 - 258 mm (10.2 in) torque converter and heavy-duty gearbox and differential (see 4T65E-HD)
MD7 - 245 mm (9.6 in) torque converter (Chinese version)
M76 - 245 mm (9.6 in) torque converter (with all-wheel drive capability)
You will want a match these RPO codes.
SECOND is the final drive ratio. The PCM can detect the difference, and in some cars may not engage if the correct final drive is not present. Here are the RPO codes for the four different final drives used in the transmission.
FQ3 - RATIO TRANSAXLE FINAL DRIVE 2.86;
FR2 - RATIO TRANSAXLE FINAL DRIVE 2.93;
F83 - RATIO TRANSAXLE FINAL DRIVE 3.05;
FR9 - RATIO TRANSAXLE FINAL DRIVE 3.29;
To narrow year search for potential cars, the following site have pretty good info on the final drives used on various cars. Click on the years of the cars in question.http://www.gmtuners.com/transmission/index.htm
THIRD is the converter stall speed. There will be small differences for most cars as it is based on car weight as well as final drive value and engine ratings. Reusing the cars original torque converter will address that area. Some indication of stall speed value is given in the K-factor information in the above gmtuners page. This bottom of this page from the gmtuners website will show you how to decipher the four digit code on the torque converter. http://www.gmtuners.com/gmtransinfo.htm
FOURTH, the torque converter needs to have the correct lockup clutch friction material for the PCM that controls it (regardless of HD nor not). This changed over the years. The newer ones can be used on older transmissions with calibration changes, but older type in newer transmissions will fail. Reusing the cars original torque converter will address that area.
FIFTH is area is electrical compatibility, and this is what trips up a lot of guys. 3 different electrical interfaces to the transmissions were used from 97-08. Some of these differences had to do with how the PCM determined what gear the transmission was in, or was commanded to be in. If you look on a GM parts web site, you will see that three different internal harnesses are available for the 4T65E. Each of the three harnesses is listed below along with the cars that use the harness. Your car and the donor car will have to match. If you have any additional insight, please leave me a comment and I can correct this post.

1999 Pontiac Grand Prix GTP. Mileage 132000. 1 to 2 shift normal. Trans. will not upshift into 3rd. gear, goes to 4th. It will downshif to 3rd. from 4th. When the trans. get hot from stop and go...


If tranny fluid is clear and at normal level, then the issue is with the transmission - it is getting ready to go sayonara.

Better get that fix before you get stranded.

When shifting from second to thrid it has a skipping or bucking.drop transmission pan,no metal or shavings in pan


You should have the computer scanned at a transmission shop or a dealership. If you get a code P1811, that is the 'max adapt long shift' code. That means that the Electronic Pressure Control solenoid may be going bad. Normal wear and tear on the clutch material can also cause this code. Basically, it means that the transaxle is taking longer than 0.65 seconds to shift, and the computer commands maximum line pressure to avoid burning out the clutches. I have had good success with installing a shift kit on several of these transaxles (4T65e) to remedy this problem with no further issues. Visit www.transgo.com and look for distributors in your area. The shift kit you need is the SK 4T65e shift kit. The kit comes with very good instructions. It is not a difficult job. If you can drop the pan and change your own fluid, you can install this kit.

Some owners of the above models equipped with a Hydra-Matic 4T65-E transaxle with a Julian Date prior to 0045 may comment on a whine noise in PARK and/or NEUTRAL or a Service Engine Soon or Service Vehicle Soon lamp that is illuminated. Upon investigation, a DTC P0741 or P0742 may be found.

Cause:
The above condition may be due to drive sprocket support bearing fluting and/or bearing failure.

Correction:
Replace the drive sprocket support bearing. Inspect the channel plate and drive sprocket for any abnormal wear, Turbine shaft for cut seals and/or nicks, and chain for excessive play due to failed bearings.

Important:
When installing the new bearing, the part number MUST be visible (facing upward). Before installing the drive sprocket, lubricate the bearing assembly with J 36850 assembly lubricant.

Refer to the 4T65-E Unit Repair Section for the installation procedure.

Service Part Information:
Part Number: 24214158
Description: Drive Sprocket Support Bearing


Parts are currently available from GMSPO.


Its possible that you can use a voltmeter to test for power and ground at the TCC solenoid connector and also resistance across the solenoid. The scan tool is helpful in pulling the codes, commanding the TCC on and off and monitoring the state of command while driving.

Hope help with this (remem,ber comment and rated this).

Will a 1997 pontiac bonneville transmission work


THAT CAN BE THE CASE, THE GEAR RATIO CAN BE DIFFERENT, JUST AS THE REAR WHEEL DRIVE CARS, AND YOU NEED TO BE CAREFUL. THE ELETRICAL CAN BE DIFFERENT ALSO, GET THE SAMME YEAR, MOTOR SIZE.
