AWF8F35; GA8F22AW; 8F45; U880F; TG-81SC
Introducing the world’s first front wheel drive 8-speed transverse mounted automatic transmission developed by the Aisin Group called the AWF8F35 (Figure 1). This transmission is currently being used in BMW, GM, Toyota/Lexus and Volvo applications. Each manufacturer using this transmission will assign its own designation. BMW calls it the GA8F22AW transmission. GM refers to it as their 8F45. Toyota/Lexus calls it their U880F transmission, while Volvo refers to this transmission as their TG-81SC replacing the TF-80SC. The transmission used in this newsletter is a U880F.

To assist you in having some technical information to become familiar with this widely used transmission, a component application chart can be seen in Figure 2 while Figure 3 provides solenoid location and identification. Figures 4 and 5 show the valve line-ups in the valve body with valve and spring I.D. in Figure 6. Figures 7 and 8 show small parts locations in this valve body with Figure 9 giving to case passage identification.

Solenoid and TFT Specifications:
The SL1 and SL2 Solenoids are normally closed solenoids blocking pressure to their respective circuits. These two solenoids measure 11 to 15 ohms at 68° F.
The SL1, SL2, SL3 SL4, Sl5 and the SLU solenoids are normally vented solenoids venting pressure in their respective circuits. These solenoids measure 5.0 to 5.6 ohms at 68° F.
The SLT solenoid is a normally applied solenoid supplying pressure to its respective circuit. This solenoid measure 5.0 to 5.6 ohms at 68° F.
Basic TFT resistance range will be 5 to 8K at 50°F and 0.22 to 0.28K at 230°F.
