The Buick Riviera was highly lauded as one of the best luxury cars ever made, featuring sleek body styles and features like graphic controls that were revolutionary for its time. So it can be quite frustrating if your Riviera would suddenly refuse to go into reverse. If the Riviera does not shift to reverse, there is definitely something wrong with the transmission. However, what this \"wrong\" is can be due to several factors, including:
One of the first things you need to check when Riviera doesn\'t go into reverse is the transmission fluid level. Transmission fluid diminishes gradually over time, and once the level gets too low the transmission and the engine will start to seize due to the lack of lubrication in the gears and increased temperatures. So if the temperature gauge also goes up, and you start to smell burning hydraulic fluid, there\'s definitely not enough oil in the transmission.
To check the transmission, pull out the transmission fluid dipstick next to the engine oil dipstick. If the fluid level on the dipstick is well below the fill indicator, the transmission fluid needs to be refilled. Also, take note of the color and consistency of the transmission fluid. If the fluid appears clear and has a red, pink, or amber color, it is still in good condition. However, if the fluid appears burnt or contains particles, it has gone bad and must be drained out and replaced with a new batch.
On the other hand, if the transmission fluid level remains low even after attempts to refill it, there may be a leak somewhere in the system. Leaks do tend to sprout in transmissions of older cars, although lack of maintenance can significantly speed it up. Either way, a leak in the transmission is a serious issue that must be addressed immediately. Aside from rapidly draining the transmission of fluid, it could let in harmful contaminants such as oil, dirt, and rust that could damage various gears and other mechanical parts.
If the transmission refuses to shift not just in reverse but also into another gear, the problem may be due to the gear shifter. The shifter can get stuck to a specific gear or refuse to shift to one because the gears are blocked by dirt or other type of residue. Having the gears cleaned by a mechanic should fix this problem, but if the gears are already too worn or damaged, they must be replaced as soon as possible.
A loose throttle cable can also be the cause of the transmission refusing to go into reverse or shift gears. Located in the engine bay, the throttle cable is braided tightly and stretched at a specific tension at the factory. But as time passes, the constant stress on its strands can cause it to come loose. Changing or modifying any of the transmission\'s parts have also been known to increase the slack of the throttle cable. And once it does become too loose, the shifter may not be able to move the gears properly or not at all.
