The valve body is considered the nervous system of the transmission, it is responsible for converting the electrical signals from the TCM into hydraulic actions. The 42-RLE uses a non-synchronous, clutch-to-clutch design. This means that the shifts from gear to gear must be timed perfectly thereby releasing and applying a friction clutch to achieve a flawless shift.

Because of the sensitivity of the hydraulic circuits, we heavily modify many areas of the valve body. Hydraulic oil flow is ported to certain clutch packs where additional pressure is needed. The accumulator piston seals have been redesigned to ensure hydraulic pressure integrity. We increase converter charge pressure and volume to reduce the trans and converter temperature.

The ATS 42-RLE valve body can be purchased separately and installed in a stock transmission or any aftermarket transmission for increased transmission performance and reliability. On the 2003 to 2006 42-RLE models all line pressure modifications are taken care of inside the valve body so you do not need to install the ATS Co-Pilot on these years like the 2007 to 2011 models!

Mostly great, except one little annoyance
Color: Black&Silver, Color: Black&Silver
Pros- lightweight, small, very accurate, easy to clean, timer included. Cons- I use this to brew espresso on my Breville Touch and to get an accurate reading, you have to place something flat (structured) under the scale. Otherwise the reading just jumps all over the place. I know lot of espresso machines have the same base, so this might be an issue for some! This is my reason for 4/5 stars. It’s an easy fix, it’s just kind of annoying. Value for the price seems to be on point. It’s easy to clean. It has a timer as well as scale (nice for espresso). Buttons work the first time you push them. That’s it that’s all

A solid upgrade!
Size: 53mm, Size: 53mm
This coffee tamper has been such a nice upgrade to my espresso routine. It has a solid, balanced weight that makes tamping feel smooth and effortless, and the textured grip gives it a really comfortable, secure feel in hand. There’s something satisfying about how neatly it presses down the coffee grounds—like it was made to fit perfectly. Since I started using it, my shots have been more consistent, with a beautiful crema and better flavor overall. If you’re looking for a tamper that’s simple, well-made, and does its job really well, this one’s definitely worth it.

It's pretty

I've never had a tamper, I don't know what I'm doing. But it seems to work just fine and I like the wood.

solid precision built. weight shy of 17oz (478g), aesthetically pleasing. the plunge operation quite smooth. took one star off per its one spring design, you tamp with whatever weight you put on it.
