adaptive shift learning

[dbaxter_ss]

I have a quick question on this. After flashing my gto shifts just great. Nice and smooth after about 2 weeks its practically snapping my neck.

Will setting this to 0 for normal mode and setting the RPM and/or VSS upshifts stop this?

Even when I was setting this down more to shift sooner, about 2 weeks after the tune, once again its taking its time shifting and then engages snapping the drivers neck

I am assuming yes after seeing that the 3-4 shift times are already zero'ed out and that is always nice and smooth.

What did you set the following to...?
a. the shift times for each shift,
b. the PCS current for each gear.
(Can you post screen shots from the tune tool).

Is the TCC locked (...that you know of...) during the 3-4 shift...?
What other transmission parameters did you alter...?
What mods do you have on your Goat...?

Also, be sure to check the ATF level before doing anything else.

When you say "takes time shifting", is the shift delayed, or is the shift laboured (dragged) out...?
When you say "smooth" do you mean that the shift has little or no "feel"...?
When you say "snaps neck" do you mean the shift has a very firm feel...?
Or is it even firmer than that (I take it your tyres lose traction for a few seconds... ...)...?

Does it snap neck when upshifting or when downshifting...?
When this happens, how much throttle is being applied...?

Capture a log of the Last Shift Time, Last Shift Error, Current Gear, Box Ratio, and PCS current (along with VSS, RPM, TP, MAF, MAP for correlation);
if you can, capture before and after the problem, and post images of your logs.
