Z-Gate Shifter
Just wanted to make a quick review to say I am really impressed with this shifter, the installation was pretty simple with very descriptive instructions. It's perfect if your want to upgrade and not spend a lot, I would probably spend more if I was building a race car but I just wanted to upgrade to a floor shifter for the street.

Good Quality Pan
It's a good quality pan with nice deep heat sinks , I cannot give it a "5" because the factory drilled and tapped hole for your Temp. gauge will only work with an electronic sensor. The hole is too small for a mechanical gauge which is what I am running ( AutoMeter mechanical Temperature gauge ). Fortunately the pan has a substantial boss around the hole allowing me to drill and tap a larger access hole that my mechanical sensor can pass through . I'm also running an AutoMeter psi gauge but that is teed in between my twin Hayden coolers and the factory trans pressure regulator. So the two extra quarts of fluid the B&M pan provides plus the one extra quart from my twin Hayden coolers , when pushing my 600 HP SRT 392 hard I barely hit 200 degrees and that's with a 2800-3000 rpm stall converter . Normal driving around town the tranny stays at about 170 degrees and this is in 90 degree Florida heat . So I am very happy with my pan/cooler setup.

Great to Have This!
The only place I have found a locking trans dipstick for my Chrysler 300. A little overpriced but great to easily check fluid level for the first time ever! Don't understand the manufacturing decision to not include a dipstick with the car. Very snug pushing in and locking for the first time but better to have a tight fit!
