*by M***. on March 8, 2018*

Very well written manual, as I would expect from ATSG. This book does have it's issues, but not at the fault of ATSG, but at the fault of the different manufacturers who use this transmission, Currently GM, Saturn, Nissan and Volvo. Each manufacturer has their own specification and as such, the possible combinations and differences of the setup of this transmission vary DRASTICALLY. Do your RESEARCH based on which vehicle this unit came out of and you;ll be OK!
