4l60e slips in all gears

Hi all,

my 4l60e slips in every gear when wot, otherwise shifts nice when not under load.

I have placed a pressure gauge and does not move from 55 psi in all gears including reverse.

what could be the issue? Has anyone come across this?

thanks for your help,

What mileage is on the trans? Maybe your clutch packs are worn out?

Have to put a scan tool on it and looked to see if the PCM is commanding the EPC to increase the line pressure? I'm sure you have all ready checked the fluid level.

Uh, 55 Psi of Line-pressure is not gonna cut it.

Time to come apart.
