do they sell an o ring kit or just need to match them up

Thanks .Any idea where the regulator is located and is this something I can repair without taking to the shop

Need Help!! I have a 1982 Mack r model with a 12 speed maxitorque transmission it started leaking air out the exhaust line on the shifter when I put it in high range, I thought it was the shifter knob so I bought a new one and that didn't cure the problem. I was able to drive in low range with no problems but now it is starting to leak out the exhaust line when I put it in low.
