When you buy a BC Automotive 4R70W valve body kit, you are not just getting something that you can feel. You get something that your transmission will thank you for. Our modifications eliminate the excess clutch slippage that create so much of the heat that is deadly to a transmission. The changes we make are particularly critical for older model transmissions to provide enhanced fluid flow to critical components to ensure longer life.

Our valve bodies are modified without using any of the “tricks” and add on parts that so many other companies use to get the shift feel that they want. We prefer to do it the right way. The safe way. We make internal changes to provide critical fluid flow to charge and release all of the transmission components properly and supply the correct parts to give you the shift feel that you want. With other kits, you yourself have to drill and make permanent changes to your valve body that cannot be undone if things get messed up or you later decide that you want to step it down or go back to stock. With our kit there is no chance of making a mistake by drilling in the wrong place or using the wrong size bit because all of this work has already been done for you. 

Our complete valve body kit is just that. We provide a complete valve body that has been disassembled, cleaned, inspected and modified to your specification. The kits also come with all applicable accumulators and caps, the proper accumulator spring setup for your application, necessary gaskets, a filter and detailed directions. This kit has it all. The only things you will need to supply are the time, tools and fluid.

As a bonus, you have the option to keep your old valve body. This means that if you need to put the car back to stock  for whatever reason, that you have everything to be able to do that quickly and easily. This comes up more often than you may think when people decide to sell their car.

This complete kit is priced at $225 for 1993-1995 models, $250 for 1996-1998 and $300 for 1999-200X models. There is an additional $75 refundable core charge on all valve body kits that will be returned to you upon our receipt of your old valve body.
