Once the transmission is sitting on your workbench it take less than 30 minutes to disassemble. looking at the clutch packs I think that I may heave bee short changed on the number of clutches shipped with my
eBay purchase.
The 4L60E is an easy transmission to work on with no hidden tricks.
In addition to the Corvette servo upgrade and shift kit already purchased I may also get the Sonnex Smart Shell which is beefier than the OEM drive shell.

Solves Multiple Problems in All Performance Applications In GM 4L60, 4L60-E, 4L65-E and 4L70-E units, bulky after market shells always fall short when splines continue to strip and the shells break under stress. A chronic problem with both OE and thicker after market shells is failure of the rear planetary bearing. From daily jobs to extreme builds, the Sonnax Smart Shell heavy-duty reaction shell kit 77749-02K is the only way to prevent shell failure AND protect the bearing.
The Smart Shell avoids the weight found in traditional, heavy-duty after market shells thanks to a unique combination of improved design and manufacturing for a super strength shell that's only slightly bulkier than OE. To prevent thrust loads from overwhelming the captured planetary bearing, the Smart Shell features a larger bearing and custom roller clutch race. These parts re-route thrust loads through the carrier, completely bypassing the delicate bearing.
- Stops spline stripping
- Prevents hub breakage
- Eliminates planetary bearing failure
