Speedometer Clamp 4L60-0044L60-004
The speedometer gear to drive a speedometer cable when installing the 4L60-E electronic transmission is held in place with a clamp assembly (Stealth Conversions part #4L60-004). A closeup is shown below.
RELUCTOR RING AND COLLAR CLAMP
As shown above, the governor ring has a slight crown, which requires that it must be installed with our collar clamp #4L60-004 oriented towards the front so that the clamp is directly over the crown of the governor gear and will not slip off.
More information on alternative ways to drive a speedometer cable on the 4L60-E transmission is available in the book, Chevrolet TPI & and TBI Engine Swapping.
