The transmission hangs in first gear and the rpm's go really high. You have to let off the gas completely and let the car idle along and it will change into second gear within thirty seconds or so. The problem seems to be worse when the car has been parked overnight. Once it has been driven for a few miles the problem usually does not happen again until you park it and get back in. All other gears change out smoothly. Please help!

It sounds like the catalytic converter might be plugged causing the vacuum reading to be off making the transmission shift late. Here are two guide to help you figure out the problem:

Thank you so much for these guides helped me find the catalytic converter was bad. I had it replaced for $540.00 all fixed. I love this site.

May want to look at this as well. Neutrals at stops, shudders on takeoff: One of the most common problems I have found after the mileage gets over roughly 60,000 miles. The scenario. You are driving in traffic for a while or your car has sat for a while and is a cold startup. You put the car in drive range and it will not move, or if driving you come up to a stop light and in heavy traffic and the light turns green and surprise! You are holding up traffic with a car that will not go anywhere. The most common cause of this problem is a worn out inner surface of the Input clutch piston. I will post pictures soon so you can better understand why it is a real problem. Once the inner sealing area wears it can prevent the inner lip seal for the piston from sealing properly. You may find that revving the engine up will finally get the car to move and it will bang into gear. This is because the pump in the transmission is working harder and moving more fluid thus allowing the added fluid to overcome the leak which prevented the clutch from either initially applying or staying applied. Another area of concern that causes this is a boost valve in the valve body, not near as common but it can cause this problem on a lessor scale. If a fluid/filter service has not been performed in a very long time then a very dirty or plugged up filter can add to problems as it because a major restriction. If the filter is found to be very dirty on the inside, which can be verified by cutting open the filter, then there are other problems inside the transmission anyways and an overhaul is the only correct way to fix the problem.

I received my car back last week. The new shift kit, and check valve fixed the issue. The car is now driving better than it did when I first purchased it in 2000. Hope this helps and good luck!

Hello, I have the car listed above SS model that has had absolutely no problems until lately. It first began when the 'service traction/ABS' alarm/light came on ans then about two days later the car would not shift into fourth/overdrive. I changed the transmission speed sensor and the alarms went away and have not seen them since but the car still will not shift into fourth. I have put a code scanner on it numerous times with nothing thrown back, changed the transmission fluid and filter but still have no luck with anything. Can anyone please help me figure out what this issue is? I am seriously desperate to save my baby, but do not have the money (or desire) to take it to a shop if it is something that I can most likely fix myself. Thanks in advanced -Korey.

Hi KOREY,

Thank you for the donation.

What was the trouble codes when the ABS indicator came on?

Here is a table for possible causes of not shifting to fourth speed, (OD):

Front wheel drive automatic 107, 00 miles.

We have not had prior problems with this car and we are the only owners. We recently put fuel injection cleaner in it and now it does not run right.

The check engine light came on for about one or two seconds going up a hill and then went off. They cannot check a code unless the light stays on.

It takes off and then loses power like it is going to shut off. Then it takes off again and shakes/shudders a little.

I do not even know where to start. Any suggestions?

If the check engine light was on, it should have stored a code in the computer. I would take it to a nationally recognized parts store and have then scan the computer regardless to see if something is there.

Now, if this happened when you used fuel injector cleaner to the fuel, I would next move to checking the fuel filter to see if it got partially plugged. If may have cleaned the fuel tan instead if the injectors and partially plugged the filter or damaged the pump.

Try those two things and let me know what you find.

When driving and coming to a quick stop the transmission seems to down shift at a stop. Now when I shift into overdrive or drive it will not go into gear, but it will go into reverse and second an first. I checked the fluid level and it is fine. I checked all fuses and are good. Can you tell me what seems to be the problem, and what else to look for?

Scan for codes first.

Have a transmission professional check wiring and connections at transmission and do some pressure checks. It may be electrical or shoe shift valves have gone out in transmission.

What would be causing my 2002 Chevrolet Monte Carlo SS to shift poorly and sometimes not want to shift into overdrive?

Transmission fluid level could be the cause. Also a clogged or dirty transmission filter. At worse it could just be the transmission is going out, but I would check the fluid and filter for starters. :)
