1, 2 and 3 Digit Codes: 61

Name of Code:
60 - Inadequate Element Volume: L-R
61 - Inadequate Element Volume: 2-4
62 - Inadequate Element Volume: OD

When Monitored:
When volumes are updated as follows:

- LR - When doing a 2-1 or 3-1 coast down shift. Transmission temperature between 70 and 120°F

- 2-4 - When doing a 1-2 shift. Transmission temperature above 80°F. (110°F for 97 MY)

- OD - When doing a 2-3 shift. Transmission temperature above 80°F for 97 MY)

- UD - When doing a 4-3 or 4-2 shift. Transmission temperature above 80°F. (110°F for 97 MY) (Does not set an inadequate volume code.)

Set Condition:
The appropriate code is set in less than 1 second if the updated learned volume is below a threshold value.

Theory of Operation:
The volumes of the transmission fluid needed to apply the friction elements are continuously monitored and learned for adaptive controls. As the friction material wears, the volume of fluid needed to apply the element increases. The following are typical clutch volumes. The clutches may be damaged if the volumes are greater than the volumes shown below:

LR:35-83 OD:48-150 2-4:20-77 UD:24-70

Certain transmission mechanical problems (such as broken return springs, out of position snap rings, clutch pack clearance(s) out of spec, other misassembly, etc) can cause near-zero learned volumes resulting in setting the appropriate code.

Transmission Effects:
All MY's and calibrations - Normal operation with no limp-in

Possible Causes:
- Clutch pack clearance out of spec
- Snap ring out of position
- Broken return spring
- Hydraulic leak into clutch circuit with near-zero volume
