Our A604 / 41TE Updates and Upgrades
► Complete system correction and recalibration kit installed addresses several OE flaws. Modifications include updated servos, the PR system, and valve body accumulators.
► Exhaust hole drilled in all 2-4 pistons reduces harsh shifting.
► 4-ring stator with Teflon rings utilized for a superior seal that prevents cross leaks.
► Cooler bypass valves replaced to prevent overheating.
► New anodized pressure regulator sleeve replaces with wear-prone original steel sleve and prevents harsh shifting.
► Heavy duty planets and transfer shafts utilized to handle increased torque loads.
► Pump bolts carefully torqued with Loctite to prevent leakage.
► Remanufactured and tested solenoid block.
► Inspected and updated switch valves ensure proper shift quality.
► Custom one-piece OD hub bushing improves lube control.
► Completely remanufactured pump with new line bore bushings eliminates leaks and provides superior flow and durability.
► Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
► Complete road simulation using a dynamometer testing program called C.A.R.S. (Computer Aided Road Simulation). Every transmission is cold and hot tested before shipment.

A604 / 41TE History
The A604 (also called Ultradrive 41TE, 40TE, 41AE, 40TES) is a 4-speed automatic transmission from Chrysler Corporation. It was produced starting in 1989. It was originally paired primarily with the Chrysler 3.3 engine in vehicles with transverse engines.
The Ultradrive A604 was produced at Kokomo Transmission in Kokomo, Indiana, a plant which still makes front wheel drive Chrysler automatic transmissions.
The Ultradrive was a significant technological advancement in transmission operation, one of the first electronically controlled automatics. It pioneered many now-common features such as adaptive shifting. It earned a reputation for being unreliable. The transmissions were designed to use a special fluid (Type 7176, also known as ATF+3, now superseded by ATF+4) and many owners reported failures from the use of Dexron, as well as temporary issues which were resolved when the proper fluid was added.
There may also have been mistaken impressions of failure due to the “limp home” feature. When the computer sensed a problem, such as a sensor giving an inappropriate reading, a code would be stored in the car’s computer and the transmission would default to second gear only, under transmission computer control, so that owners could still drive to a service location for diagnosis and/or repairs. This could have caused perceptions of failure and premature replacement.
The 41TE transmission which directly replaced the Ultradrive had a similar design and could be considered an evolutionary change, but it included different valve bodies, solenoid packs, sensors, and other components to increase reliability. This line was also given a flash-programmable TCM and, in 2006, a variable line pressure hydraulic system was phased in, which boosted performance and longevity.
