I have a 97 bonneville and the lockup converter makes the vehicle chug when the trans gets to operating temps...it is very annoying...is there anything that can be done to solve this issue...i live in east tn and the mountains and hills make the problem worst...i have taken it to a gm dealer and had them install a chuggle program that gm created when they realized they had a problem with this trans in vehicles in mountainous areas..any other suggestions?????

Re: 1997 pontiac bonneville lock up converter
If you converter is blocked up or clogged take it to s hop and have them cut it off and put in a new one...... with a clogged doncverter it will act like it is the transmision when it is not.... i just went through this with my suburban

soulds like you have a tork converter thats locking up..you can unhook the wires to the tork converter...this is stop it from locking in...the trans will still shift...it just wont have the lockup converter working..its supposed to save fuel...but i had one i drove for many years with it unhooked and didnt make any difference
its an internal trans mission problem. pump or even torque converter issue. If they can have them run a full computer diagnostic on the transmissiop. (preferrable taken to a transmission specialty shop or the dealership)
NOTE: You must have the correct part number on the remote for it to work. The part number you need is 15732803. Transmitter programming per the GM manual: Before entering the programming mode, verify the possession of all the transmitters you will be using on the vehicle. Once you program the transmitter, the memory erases the other transmitters. You may program up to 4 transmitters.
Turn OFF the ignition switch
Usa a fused jumper (3 amp is sufficient) and connect terminal 8 (back/white wire) to terminal 4 (black wire)
Close all the doors
Turn ON the ignition switch / the doors will lock
Press and hold the following buttons on one of the transmitters for 30 seconds: lock and unlock
After a 30 second delay, the doors will lock and unlock Important: DO NOT turn OFF the ignition . If the switch is turned OFF the first transmitter becomes inoperative.
In order to program extra transmitters repeat Step 5
Disconnect the fused jumper wire from the data link connector
Turn off ignition
Verify functions of all programmed transmitters.
This should work for the 1997 and 1999 Bonneville's. Good Luck. Keep me posted, be glad to answerer any other questions you may have.
If you can find the lead that operates the lockup solenoid in the transmission, you could cut it, but I would not recommend that. Likely the converter has an internal failure. Further operation can cause more fine metal (from broken part) contamination to circulate into transmission and damage can be costly!!!
A GM dealer should be able to reflash the PCM to help alleviate the chugging.To a certain extent,it is normal,and you might want to consider tuneup things like plugs and wires,air and fuel filter,and also have all the engine and transmssion mounts checked for weakness,as weak mounts will magnify these types of problems.
