Time consuming but not difficult. The instructions are thorough. It took me about 2 hours of taking my time. Everything works exactly as it should with a s*** kit. My only complaint is the drills that come with the kit are garbage.

Not impressed! Not much more than stock shifting, a lot of work for very little pay off.

These shift kits are a joke for the rv/towing application. It's basically a separator plate and a plug for one of the valves and two gaskets. it come with two bent drill bits to drill holes in the plate. So basically you are taking the transmission apart for that. Only good thing is it actually is easy to install because you don't have anything to put together

yup ... i have used these for years .... if ya can read and do your own oil changes ya can do it in the driveway. just use a cookie sheet to do it on so ya don't lose any of the check balls and springs.
