4L60E / 4L65E / 4L70E Tail Housing Kit
Mechanical speedometer drive and factory shifter location for the 4L60E family.
$850.00
Machined tail housing that gives a 4L60E, 4L65E or 4L70E a factory mechanical speedometer take-off while keeping the shifter where the original transmission put it. VSS capability is retained, so nothing in the stock harness has to be cut or fooled.
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.
