The transmission control module is located inside the transmission housing, instead of being located outside it. Gear changes are accomplished by one clutch engaging the instant the clutch from the previous gear disengages. The shifting of gears is managed by a sophisticated computer programme which oversees a clutch-to-clutch actuation. This combination is known as a Lepelletier arrangement.
Its combined use of a conventional 5-pinion planetary gearset and a compound Ravigneaux gearset makes it incredibly light and compact. Keep in mind these are mini-mum and maximum pressure specifica-tions. Because the AWF-21 is an Aisin trans-mission, this unit has several taps for checking clutch apply pressures (figures 8 and 9). It measures 358 mm in length and weighs 90 kg. Introducing the New Aisin-Warner 6-Speed Most Ford-produced transmissions only have a tap for checking line pressure, and maybe a tap for EPC pressure.

The design team set out to create a 6 speed automatic that fits in the same space as a manual gearbox. It is also called the TF-80SC and TF-81SC. It is designed to handle a maximum of 450 N⋅m of torque.

Refer to vacuum test locations on all covers.The Aisin AW TF-8# SC series is a 6-speed automatic transmission designed for use in transverse engine applications and produced by Aisin Seiki. Both the vacuum test and clutchġ2=Normal 11=Normal 14-18 =Post repair 14-18=Post repair So, the car owner must be careful when changing speed and modes of the transmission. The valve body damper/accumulators pre-charge all circuits.Ĭlutch Piston Stroke (use selective flanges)Īdjuster: By sealing this with Loctite orĬutting o-ring groove. Transmission AW TF-80SC / 81SC has a complex structure and fully operated by the automatic system, this was the only mechanical connection with the gearbox selector. Skip Shift: Four elements controlled Controls the apply & releaseĪ balance area opposes clutch apply pistons. Pressure is adjusted to eliminate the slip at the end of the shift. Torque Phase: CAN & adaptive strategy timingĪfter initial apply, RPM vs. Servo Actuating: Reduces gear shift lag by prim. OE suggests if the print mark is not legible the friction plate should be replaced and a new pre-soaked friction installed. The B1 band should be pre-soaked with the correct fluid for 2 hours.įaced clutch plates have a print mark. The C3 clutch drum onto which the B1 band applies, has a special surface finish and should not be altered. Split band has a print mark between the straps near the anchor. Stage 2: Engine torque reduction.Ĭlutch piston travel is critical and set by selective flange/snap rings. Stage 1: 127C (260F) shifts become later and TCC remains applied longer.
TCC apply & normal clutch apply release strategy. Has 3 distinct temperature modes of operation. Temperature sensor is extremely critical to proper shift strategy and adaption! TCM The double wrapped band has special oil grooves to reduce heat. Grooves in the band drum are critical to the timing for apply and to reduce heat.
TF-80SC utilizes a brake band, TF-60SN uses a B1 clutch.

Software has been reduced by 45% over 5 speed and parts by 27% with a gain That feature is combined with fast adapts and CAN feedback. The end of the bore opposite the solenoid. The control pressure curve of each circuit is affected by the adjustment screw on Each clutch apply or release is controlled by one solenoid and valve circuit. Volvo models with Aisin Warner TF 80SC and. This is accomplished by designing a compact hydraulic circuit that remains pre-charged. Mazda M-V with Aisin Warner 6-speed on CX-9 models Volvo models with Aisin Warner 6-speed transmission. The units have the ability and programming for 2-4 4-6 upshifts and 6-2, 2-1 5-3, 3-1, 4-2 and 2-1 downshifts. Skip shift scheduling controls 4 clutches simultaneously. TF-60 went into production in the 03 Beetle (09G) with torque capacity of 280N.m. AW/TF-60 was designed in 02 along with the rear wheel drive unit, the TR-60SN.īoth units use similar power flow & control.
