Good customer service

The customer service was amazing, but unfortunately I needed it due to one of my gallons of trans fluid being cracked. Likely happened in shipping. Everything else came intact and packaged well.

Installed yesterday, worked out well. Wouldn’t let me order without adding drain plug and magnet for some reason. Three gallons of fluid would have been enough but installed a new trans cooler so ended up a quart shy.
Installation was easy, fluid was still 135° because I was impatient. The one bolt to the filter lock (8mm) off the valve body has to be tightened with a wrench, tight fit.

Great product would definitely buy if you are thinking of more fluid and better cooling!

Great kit fluid made a difference and bigger pan for more fluid wish I had done it sooner
