This includes the kits you will need to open your transmission and replace all those worn seals (and there are over 40 of them!). If you wonder why your transmission isn't shifting well or performing poorly, think about all those worn, hardened sealing rings and O-rings from age and heat. This kit includes all of the first four kits listed in the related products below. Read each of those for more detail, and, of course, any one of them can be purchased separately. Watch the following three YouTube videos. Kent will explain and demonstrate how the transmission works, so you will have a better understanding of what happens when all the seals start to shrink and harden, and fluid pressure is lost inside the transmission. Just look off to the right and see how many videos come with this tip at no extra charge; you will find almost 5 hours of videos. Explain the process of taking apart the transmission, installing all the seals and O-rings properly, and putting it all back together. He will take the mystery out of these transmissions once and for all.
Product Details
PLEASE NOTE: The included video instructions do not cover valve body overhauls. You will get the accumulator sealing rings without instructions. There is lots of information with schematics online on opening, cleaning, and resealing the valve body. There are other parts you may need when you open up your transmission. Most often, on high-mileage transmissions (over 200K), you may need to replace some of the clutches and steel plates. We don't carry these parts, but you can find them online with a thorough search.
This COMBO KIT includes the first four kits listed below. Click on and read each one to fully understand what is included in this master reseal kit.
