Reprogram Transmission Shift Points.....

[linuxnut]

I am wanting to reprogram the Transmission Shift points for 2nd-3rd and TQC Lockup.

My pathy shifts from 2nd to 3rd around 3,000 with a very light throttle. I was wanting to keep it at or under 2,000. And also move the Torque conver lockup down to 45mph.

is there a standard reprogram ROM that can acheve this or will i have to get a custom ROM for the ECM?

Can you verify the shift points now, using a warmed up engine and transmission, level road and light throttle.

Experiment at least 3x and record the speed you do when each gear shifts, but a level road is needed.

How much distance is on the transmission fluid? Are you sure you reach and use each gear, does RPM make sense for the gear you think you are in?

You can do this same test by driving along and keeping your RPM at or below 2000 with every gear change up to top gear, stay away from freeways when doing this, most people get ticked off when you drive sensibly.

It is very easy to drive at 3000 RPM, but keeping the revs below 2000 RPM, takes effort and restraint.
