Anytime you open the lines to replace parts the receiver dryer should be replaced. Moisture in the lines is unacceptable, and it is the R/D's 'yob to remove it to an acceptable level. The system's yob is to compress freon gas and then extract heat and change phase into liquid, then the whole cycle again and again 'till the end of time.

Update, Im so stuppid, I finally propperly cleaned the AC condencer thats in front of the engine radiator, it looked clean at first glance but after i removed the screens and could see between the two i found it was clogged full of dirt. anyway I mowed for 4 hours today in 100`temps and stayed cool. and to think all these days of swetting when all i needed was a water hose. anyway thanks for all your help, and some of you even told me axactly what the problem was and i just didnt see it, to be honest i confused the transmission cooler for the AC condensor for a few days of looking things over.

Glad you got the system working with just a little cleaning. Clogged condenser raises the high side pressure, resulting in the high temp switch shutting the compressor down. Once the pressure lowers, the compressor comes on, and will just keep cycling until the problem is repaired. Dirt, heat and high pressure is an air conditioners worst enemy. Keep those condensers clean. We are approching 100 degrees with dewpoint above 70. Air techs. are very busy. Has been many years since we have had this type of weather. I like it 85 or so. trac
