This is a complete performance built ready to drop in AOD transmission for the '89-93 Thunderbird/Cougar owners.
The Stage 2 AOD trans is capable to 450 HP. This is the strongest TWO PIECE input shaft transmission we consider to be reliable. It is fully rebuilt using '89+ AOD cores. Each unit is fully inspected for wear, all gaskets and seals are replaced with quality new pieces, and final clearances are adjusted for performance use.
Included in the Stage 2 AOD is a performance Series 1 valve body. It is the first step to solving the annoying AOD shift overlap, early shift points, and sloppy or erratic shift firmness levels. The Series 1 has been a huge success. Every valve body is custom modified using our own parts – no off the shelf kits. Each valve body is modified to increase line pressure and provide full time torque converter charge with constant cooler flow and lubrication. Each unit includes several new or modified spring assemblies and custom separator plate modifications.
These modifications increased wide open throttle and part throttle shift points in ALL gears – with additional custom modifications to help push 2nd gear to a healthy RPM (unlike many other kits or stock applications). Shift overlap and flare is eliminated and shift firmness is tailored to your desire. As a standard baseline, the Series 1 valve body is adjusted for a 5,800 RPM shift in all gears at wide open throttle, and retains the stock shift pattern.
The newest addition to the Series 1 valve body allows complete user control of the wide open throttle shift point. Simply drop the pan and turn a screw! It allows you to customize your own wide open throttle shift point within an 800 RPM variance. Each valve body is also boxed with a new 2/3 accumulator valve and a new governor valve. The valve is critical for correcting gear ratio effects on shift points, and is a perfect combination for those running 3.73 gears or deeper
NOTE: A Series 2 valve body is optional for an additional $199.99. The Series 2 takes all the advantages of the Series 1 valve body and adds an overdrive lock-out feature. This is the most versatile valve body we offer for the AODs. The shift pattern is altered so that the user can command each gear separately, and has a 12 volt solenoid for overdrive engagement. No more “1-D-1 Shuffle”!!! This VB can be shifted manually to higher gears while the lower gears maintain fully automatic function controlled with TV pressure. TV adjustment is as simple as hooking up the cable – delicate procedures are not required. A switch kit is not included.

A $250 core charge in addition to the purchase price applies to this transmission. This cost is refunded when your old trans is returned. Truck/Freight shipping will be approx. $300 +/- to the lower 48 states.

Call us to purchase this transmission as we will need to discuss how your car is modified so we can best custom build your valve body and also make recommendations for a torque converter that can be purchased separately. 513-697-6501. NOTE: These are custom built to a customers order and will typically take 3- 6 weeks depending upon how busy our builder is. A shipping charge does apply and can be quoted prior to ordering once we know your zip code.
