A transmission repair is fixing the problem at hand. This is usually the most inexpensive way to go as it does not require removal or disassembling of the entire transmission system. Only the parts causing trouble are removed and replaced.
Transmission repairs do not include disassembling, cleaning and inspection of the valve body or pressure testing the torque converter, as commonly seen in a FULL rebuilt transmission. A transmission repair carries a shorter warranty up to 12,000 miles or a full year, at the discretion of the shops that carry out such repairs.
The essence of a transmission repair is to fix the current problem. However, the transmission may still have weak internal parts which could lead to yet another transmission problem in due time.
