I had a 97 "vic" that down-shifted hard and just didnt feel right. I had quite a bit of success in changing the trans fluid and filter myself. Some quality additives also helped. I would suggest "Dr. tranny shudder fix". sounds weird but the stuff does work.... note : when you pull trans pan and change filter dont be alarmed if you find a plastic plug in the pan. Throw it away, it is used to block debris down the filler tube on the assembly line.
Bad transmissions can have several symptoms. The Tahoe could shake, or not go into gear properly. The vehicle can suffer fuel economy, or have trouble driving at speed due to the transmission slipping.

Trouble code P1870 means: Transmission Component Slipping (4L60-E, 4L65-E, 4L80-E)
Some of the early signs of transmission trouble will be gear slipping (this is usually felt as a jerk of the car when it changes gears), or loud engine "reving" as it start to take off. Some transmissions fail in the top gears which means that you wont be able to get to your top speed.

You can tell if the transmission is bad on almost any car by looking for jerky acceleration when driving, especially when moving from low to higher speeds. If the car is jerky, or seems to be having trouble shifting, it is likely a problem with the transmission.
When a transmission warning light on any vehicle turns on, it can mean a few things that will spell trouble if not checked right away. One cause is a bad sensor or the fluid is so over used, which is not so serious, and a scheduled fluid/filter change usually fixes the problem. If the color of the fluid is still red and appears to be fine, chances are that slipping is occurring in the transmission. Slipping causes friction and friction generates heat thus boiling the fluid. This is a very serious problem and a replacement of the transmission will be required if this condition is not attended to right away.

Be sure the trans is full with the proper lubricant.
Yes, you can get in trouble for driving a criminal somewhere.
Yes. Overfilling the transmission fluid may cause problems within the transmission. It could cause abnormal operation within the transmission because the fluid is not performing correctly. Transmission fluid does not compress, while air does and as a result of overfilling, the fluid could become aerated. If you're having tranny trouble, it's best to leave the fluid alone and visit a tranny specialist. They can remove the excess fluid AND determine if any damage has taken place.
