Howdy Pard -

I recently had the same situation with a short cycle clutch engagement.

I added two cans (24oz) R134 and problem solved. With the clutch engaged it runs about 55psi and with the clutch off it's about 25-30psi. The A/C works great - and cycles as it should.

Also - once you add the R134 - make sure your low speed cooling fans come on with the A/C running. In your climate making sure those fans are operational is critical. Without those fans running the A/C won't function properly (increased heat = increased pressure in the A/C system) and you run the additional risk of overheating the engine and tranny.

Good Luck-
Glenn
