Generally speaking, you can expect to pay anywhere from $2,000 to $6,000 for a manual to automatic transmission conversion. This includes the cost of the automatic transmission itself, as well as the labor involved in removing the manual transmission and installing the automatic transmission.
In addition to the cost of the transmission and labor, you may also need to purchase additional parts, such as a torque converter, flexplate, and shifter. These parts can add several hundred dollars to the total cost of the conversion.
It's important to note that converting a manual transmission vehicle to an automatic transmission is not a simple DIY project. It requires specialized knowledge and equipment, and it's best left to experienced mechanics.
If you're considering converting your manual transmission vehicle to an automatic, it's a good idea to get quotes from several different mechanics before making a decision. This will help you ensure that you're getting a fair price for the work.
