Transgo 700-LU Hydraulic Lock-up Kit for TH700-R4/4L60

TH700-R4, 4L60 Hydraulic Lock-up Kit This TransGo kit does not require any electric connection for lock-up operation. However, the kit requires the valve body to be factory machined for the inner and outer valve train that may be currently occupied by the OE dummy plugs or existing valve train. The kit can also be used to replace existing valve train for easier TCC shift timing calibration.
