Automatic Transmission - 6F35: Overview
This automatic transmission is a 6-speed transmission with electronic shift control. It is designed for operation in a transverse powertrain for FWD vehicles.
This transmission has a 4-element torque converter design, which includes a TCC and a geartrain with 3 planetary gearsets.
The hydraulic control system of this transmission uses 7 electronically controlled solenoids for:
- Shift feel (through line pressure control and shift pressure control)
- Shift scheduling and timing
- TCC operation
Identification Tags
Identification Tag Location
| Item | Description |
|---|---|
| 1 | Solenoid body identification tag |
| 2 | Transmission identification tag |
Transmission Identification Tag
| Item | Description |
|---|---|
| 1 | Transmission part number |
| 2 | Bar code 1 |
| 3 | Assembly plant line shift |
| 4 | Transmission build date (DDMMYY) |
| 5 | Transmission serial number |
| 6 | Bar code 2 |
When servicing the transmission, use the transmission identification tag located on top of the transmission case.
Original Solenoid Body Tag
| Item | Description |
|---|---|
| 1 | 13 - digit solenoid body strategy |
| 2 | 7 - digit solenoid body identification |
The solenoid body strategy is programmed into the TCM to control the shift, LPC and TCC solenoids to prevent harsh shifts. The solenoid body tag on the transmission case contains the 13-digit solenoid body strategy and the 7-digit solenoid body identification.
Replacement Solenoid Body Tag
| Item | Description |
|---|---|
| 1 | 13 - digit solenoid body strategy |
| 2 | 7 - digit solenoid body identification |
When a new solenoid body is installed, a new solenoid body strategy file is downloaded into the TCM. A replacement solenoid body tag is supplied with the new solenoid body which contains the 13-digit solenoid body strategy and the 7-digit solenoid body identification. The new tag is placed over the original solenoid body tag.
Solenoid Body Identification and Strategy
| Item | Description |
|---|---|
| 1 | 13 - digit solenoid body strategy |
| 2 | 7 - digit solenoid body identification |
If the solenoid body strategy printed on the solenoid body connector does not match the solenoid body tag, a new solenoid body must be installed and the solenoid body strategy must be downloaded into the TCM or harsh shifts will result.
Solenoid Band Number
The solenoids are calibrated from the factory and are not all the same. The solenoids can be replaced separately, but only with a replacement solenoid with a injector nozzle and band number that matches the solenoid being replaced. When solenoid(s) are replaced, the new solenoid band number must match the old solenoid band number. The band number is next to the two-dimensional matrix barcode on the side of the solenoid and will be a 1, 2, 3, 4 or 5.
