This page lists all of the specifications for all automatic transaxle models that have been available for 2.2L and 2.5L engines. Following each description is a table listing all of the technical specifications of the transaxle. This page is rather incomplete because I have no information on any other units other than the A413. If you would like to help me out, please email me.
These front wheel drive transaxles combine the clutch, transmission, and differential into one unit, thus the name "transaxle".
This transaxle was put into production in 1984(?) and was used up until 1994(?). The unit has 6 operating modes: park (P), reverse (R), neutral (N), drive (D), second gear (2), and low gear (1). The system consists of 2 multi-disc clutches, an overrunning clutch, two servos, a hydraulic accumulator, two bands, and two planetary gear sets. The usage of each component is described in the chart below. The torque converter measures 9.48 inches in diameter and is mounted to the flywheel by a flexible drive plate. In 1987, the transaxles were equipped with a locking torque converter on vehicles not equipped with a turbocharged engine. The transaxle is cooled through an oil-to-water heat exchanger in the collector tank on the radiator, and/or a standard oil-to-air heat exchanger.

Three final drive ratios are available, depending on the gear sets used on the transfer shaft and differential ring gear. Turbocharged engines that were equipped with an A413 transaxle received a final drive ratio of 3.02:1 and a different set of shift points. The table below gives the details on all shift points:
| Overall top gear ratio | 2.78:1 | 3.22:1 | 3.02:1 (non-turbo) |
3.02:1 (turbo) |

From 1984 through 1987, these transaxles are filled with 8.9 quarts of Dexron II automatic transmission fluid. 1988 and later models were filled with Mopar ATF Type 7176 to reduce wear, especially on the locking torque converter. The gear ratio information below may not be accurate for all years. From the information I have gathered from several service manuals, the values for the overall gear ratios are inconsistent. Either someone at Chrysler can't multiply, or the transfer and final drive gear ratios changed more than they documented.
| Gear | Ratio |
| 1st | 2.69:1 |
| 2nd | 1.55:1 |
| 3rd | 1.00:1 |
| Reverse | 2.10:1 |
| Final | 2.86:1, 3.05:1 |
| Transfer | 0.96:1, 1.06:1, 1.22:1 |
| Overall | 2.75:1, 2.93:1, 3.02:1, 3.22:1, 3.49:1, 3.72:1 |
This transaxle was put into production in 1988/1989.
