CVT OIL LEAK DIAGNOSIS USING FLORESCENT DYE
APPLIED TRANSMISSION: Continuously Variable Transmission (CVT)
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
||lubricants which are sometimes used to ease the assembly process.
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.
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.
