Converts a 1998-up 4L60E to a factory mechanical speedometer.
$850.00
This kit will convert your 1998 and up 4L60E transmission to a factory mechanical speedometer and still have functional VSS capability. This conversion kit features a machined billet adapter that mounts to the 6 bolt stock transmission, allowing the standard 4 bolt tail housing to bolt upright. It also includes a new mechanical speedometer sleeve with a new gear, and a reluctor/drive gear bushing assembly. This gear assembly drives the mechanical speedo and operates the VSS sensor. This is a simple 30 minute bolt-on installation.
This one is cut to your numbers. Run the speedometer gear calculator first, then bring the tooth count to checkout. Between sizes, or an odd rear gear, call 469-688-6985 and we will cut it to suit.
