Product Details

The OPT valve body upgrade package takes the best parts available and groups them into one kit, for the best results possible.  The selected parts can all be installed with the transmission in the vehicle.  Included, are all the parts needed to complete the job, minus fluid.

These kits are designed for prolonged life of your transmission with a boost in performance.  To us, these are not considered 'high performance,' but will definitely provide positive shifts and added line pressure to all gears.  This added line pressure will allow your transmission to withstand more aggressive driving, heavier towing, or just any general heavy duty uses.

Just what I needed

I had multiple problems with my transmission. The plate was completely shot. A checkball was stuck in it. Broken accumulator spring. This kit brought it back to life. Came with all the gaskets and filter, so worked out well during a service just to install it. Also, the shift kit came with instructions. Would recommend.

I bought this package in January of 2017, and recently had it installed. I can definitely notice a difference. The mechanic said the ball bearing was sticking in one of the plates because it had worn a bigger hole in the plate. He said he could feel this when he drove it. He also said when he drove it after the work was done he could notice the difference. He was very pleased with the way it drives and so am I. I look forward to putting a few more miles on it. Even though I've only driven it a few times since the work has been done, I definitely can feel a difference. It seems more responsive and I feel the shifts when I couldn't really feel them before. It just seems more fun to drive. I'd recommend this package to a friend and I'd do it again myself. Very pleased with the product and the customer service from Oregon Performance Transmission.
