This transmission upgrade did wonders for my automotive project. As a result of my tests I determined that the Lokar SK 6852 Piston 700 R4 Transmission is a top performer in its class. It shifted effortlessly between gears, giving my car an improved speed and performance. THE installation process was also fairly straightforward .The only con is that it's a bit pricey, but the quality and performance make it worth the investment. Overall, i highly recommend this upgrade to anyone looking to improve their vehicle's drive train..
