This transmission system can be found in many cars, vans, and light pickup trucks; a full list is available at the end of this review.
So, it is highly important that you follow the manual and work step-wise. Note that the assembly process will take much longer than the disassembly. You will have to slide this to the top of the pump pocket making this clearance less than 0. The kit is made up of steel and alto graphite pieces for optimum strength and durability.
