If your transmission is slipping, you are likely worried about whether or not you are going to need a new transmission soon. There are a number of reasons why your vehicle may be exhibiting this phenomenon. The following are a few reasons.

Low Transmission Fluid Level

You will need to check the fluid level to determine if it is low. This needs to be performed on level ground, and the fluid needs to be warm for accuracy. Driving the vehicle for a few minutes will warm the fluid. You may need to consult your vehicle's owners manual if you are not sure where the dipstick for transmission fluid is located. Your owners manual should also indicate whether you need to check the fluid with the vehicle running to further ensure accuracy. If you need the vehicle to run while checking, simply keep it in the parked position and idling while you check. Slowly add transmission fluid if needed. You will need to continue to check the dipstick until it reaches the "Full" mark on the stick. 

Low Transmission Fluid Pressure

Transmissions require pressure to perform correctly. Pressure issues may be caused by the pickup tube, pump, or transmission filter. Obstructions or mechanical damage in these areas will cause insufficient pressure. Filters are an easier fix for mechanics than replacing a pump. This is because filters can be removed and replaced, but a damaged pump will mean that your transmission has to be replaced or rebuilt. Pressure problems may also be caused by an obstruction in the pick-up tube of the transmission. Your mechanic can remove the obstruction, and, hopefully, you will report the slipping issue in a timely manner to ensure that transmission does not get damaged by the obstruction.

Transmission Fluid Leak

If you have a transmission fluid leak, it is something that will need to be repaired at some point to prevent mechanical failure. Attempting to add more transmission fluid to the transmission is only a short term fix. Leaks may occur around the input shaft and axle seals. These seals can be replaced by mechanics. Axles seals will likely take a few hours to fix as long as your mechanic has the seal in stock, but input shaft seals may take mechanics 8-10 hours to fix. 

A transmission repair shop is a good resource to use to ensure proper diagnosis or your transmission issue. They can also assist with rebuilding transmissions that cannot be repaired. Choosing to rebuild a transmission that has mechanical issues may be cheaper than buying a new transmission.
