I finally finished up the installation of a 4l80e and a 3600 revmax stage 5 converter. In the tune I changed the gear ratios for the transmissions, and also increased line pressures by 10%. I also decreased shift times to around .300 seconds. Then I took off all the torque reduction management. I also left the mph that the converter would lock up, so it would drive like the old 4l60e.
On the first test drive I was surprised it didn’t shift harder. Felt a little slow and soft to me. Do I need to increase line pressure more? Or what else can I do to make it shift quicker?
Also the converter was not locking up when it should. Cruising down the road it only locked up once or twice. Is there something else I need to change to get the converter to lock up? Also it seems like it locks up very aggressively. When it did lock it felt like the car shift it kicked in so hard.
BTW, to get the tranny to work in the car I am using a pcm4less wire harness. Which is suppose to allow me to use my existing tune to control the 4l80e.
