CVT OIL LEAK DIAGNOSIS USING FLORESCENT DYE
APPLIED TRANSMISSION: Continuously Variable Transmission (CVT)
SERVICE INFORMATION
If you have a CVT that appears to have oil seepage or a leak on the transmission, follow the steps below to assist in a correct diagnosis.
1. Thoroughly clean off the area of the suspected leak.
2. Install 1 fluid ounce of J-28431 Fluorescent Oil Dye* into the CVT.
3. Drive vehicle for a minimum of 30 minutes (to ensure proper diagnosis).
4. Inspect with lamp from J-43926 A/C Dye Kit*
If no fluorescent oil trace/leak is found, the stain is probably:
^ corrosion protection chemicals sprayed on the transmission
and/or
^ lubricants which are sometimes used to ease the assembly process.
NOTE:
These may cause dust to accumulate (gather) on the transmission and have the appearance of an oil leak. Neither of these requires corrective action.
If a fluorescent oil trace/leak is found:
^ Repair using standard warranty procedures.
*These tools were made Essential in 2001 (J-28431) and 1999 (J-43926). They are also available from Tech Mate.
NOTE:
The Fluorescent Oil Dye is also available from Tech Mate in a pack of six 1 ounce bottles. That pack is available as part number J-28431-6.
