I was just wondering how much line pressure the transmission has in it and how much it can handle... I'm wondering if it is possible to put a permanentgauge on the transmission lines... Like maybe a fuel pressure or air pressure gauge... Anybody know???

 

I had my superchip pressure set too superchips setting on the premium option and my shift-points set to the limit and I blew seals in my trani after 5k miles, so I now run one pressure setting less than superchips recomendations. It has been 15k miles now with no trani problems. Which basicly means that the stock 4l60E isnt strong enough to run much over stock pressure. But I have been looking at a new beafed up 4l60E trani you can find online but they run between 1k-2k depending on internals and torque converter you order.

 

Here is gm's chart for an 02 with a 4l60e..
