Review on JET 99307 Auto Transmission Module by David Dober

Well I was (note WHAT) excited to put this in my truck for faster shifts and longer gear retention. At first it seemed like I got that. After working for a few weeks, the shifts got even tougher. The truck revved up on start and shifted in the same way as with a built-in stall, although it didn't. The most painful thing was that the truck no longer locked up in overdrive. So, despite driving on the interstate, consuming a ton of fuel. and he wants to interrupt my transmission - that's a great idea. This - and cannot return it after the 30 day period has passed. So! what a waste!
