Hiram you know what your doing and doing it well, Thanks for sharing the valuable info and video.

Very good video Hiram. This has been helpful in the repair of a tehcm on a transmission overhaul.

Another shop calls them "pillow" switches... I agree with your vacuum method being better because of the gauge indicating what is happening. more accurately. Thanks.

Hello Hi Hiram from Australia :) Thanks for sharing your knowledge and skills with us...

Un abrazo amigo Hiram Gutiérrez Aquí jhon moreno desde colombia 🇨🇴 bendiciones y éxitos 👏🏻👏🏻👍🏻👍🏻

what happens if one was put back in like that would it throw a code, shift crappy or both?

Thanks for the great video. What would happen if you continue to drive with a bad or bad pressure switches?

Hi, thanks for the great tutorial video. That was awesome. I learned a lot from you. I want to replace the pressure switches on my 2012 Buick Enclave. I was wondering if I take out TCM do I need to replace the filter plate or can I just take out the TCM without having to change the filter plate? Thanks again..

Good video. Can anyone tell please, what is the purpose of these seals (membranes/ diaphrahm)? Thanks.

Thank you master

How can I know where u are located

I changed mine out and now it went from p0989 & p0877 to p0878 . Does anybody know where I went wrong?

This video sucked. :D Thanks for the info. Home users could probably cobble something up with a set of AC manifold gauges, vacuum pump and some fittings if they've got them.
