5You too can rebuild your transmission
By Robert Austin
This is a great kit. It comes with everything you need to rebuild your 700-R4. If you are comfortable working on your your own engine, you can rebuild your transmission as well. The included directions are designed for experienced rebuilders so the Haynes GM transmission manual is a helpful resource, with lots of pictures and step by step instructions. GM Automatic Transmission Overhaul (Haynes Manuals)Various resources I've found on the web mentioned several specialty tools you may need. I discovered I only needed one, and it's a must have; the KDT2398 Automatic Transmission Clutch Spring CompressorI rebuilt mine as I had time, but all told I spent about 20 hours on it, from dropping it out of the truck to final install. If I had gotten the book when I ordered the kit instead of 3/4 of the way through rebuilding I doubt it would have taken that long to do. Take your time and do the checks they recommend and you'll have a solid transmission and bragging rights that you did it yourself! There are several web sites out there that will help with any questions you may have. Just use 700r4 as your keyword search.-Rob
