Pontiac Bonneville Lags - A/C Won't Engage

• Comments ⇓

2003 Pontiac Bonneville service engine soon. GM Computer codes = transmission solenoid

Question:
Dont to much trust the code give me dont no a lot about cars but my question to you my car lags from take off in regular drive and then around 25mph will kick into gear in first gear it takes off fine what does it sound like to you

Answer:
Sounds like a misfire. Could just be a bad spark plug, spark plug wire, or ignition coil. 3800 V6 are good for the rear plug wires to short and arc on the metal sleeve over the plug end of the wire.

You can spray so water from a spray bottle on them when running to see if you can cause the misfire. Really need the trouble code you pulled from the computer to go further.

1992 Pontiac Bonneville. Check Engine.
Question:
If I put the car in low gear it will still shift to 2, 3 just as if I put it in drive. When the car is at normal temp. And I am on the highway going 50 or 55the car will clunk as if it were trying to shift gears. It is worst in OD. But still happens in drive.

Answer:
Sounds like a 4th clutch problem. Possible spun 4th clutch shaft. Removing the pan may reveal metal debre. If so, the debre will have circulated throughout the transmission. Either way, with this many miles, it sounds like time for an overhaul, or replacement trans.
