    I googled but am still a little confused. I have to drop transmission right and take apart to get to piston right? Are there more than one piston in transmission. Sorry for newbie questions.

    So would your next step be to buy a rebuild kit and start breaking it own and rebuilding it? Would the piston be included in the kit you think? Just want to make sure I am understanding. Thanks for all the help and insight. Ravi

    I finally hook up the pressure gauge. Started I and It was around 40. When i put it into gear it went to zero and would not move. If I gave it some gas it would go creep up a little, but the pressure was very low and hardly registered. So is it rebuild time?

    I ordered the pressure gauge today. Can you tell me what pressure I am looking for? And is then when it is idle I test it or when? Thanks for all the help so far.

    Good afternoon, I do not have transmission pressure gauge. If I buy one and find the pressure is low what would that indicate? The only code I am seeing is a knock sensor.

    I Installed Standard Motor Products M14003 Transmission Pressure Switch Assembly. I checked all the plugs yesterday and still had the same issues. Before I installed the plug I had the same issues. The only thing we did was unplug the old pressure switch and put the new one in and put some...

    I have a 2005 2500hd with transmission problems. It stopped pulling and showed P1810 code, so I replaced the tranmission fluid pressure switch and put new fluid in. It ran fine for maybe 30 miles then wouldn't pull again. If it sits for a day I can crank it and it will spin the tires, but...
