I'm updating this topic as today I've managed to alter the KD(TP) lever on the transmission to a slightly longer one.
Reason for this mod was that the 1-2 shift at WOT were also a bit late.
Now with the longer lever this seems to have improved.
But, (on the contrary to what I mentioned in my post above) throttle-position does NOT alter the 2-3 shift. Nor hot or cold.
The trans still does the 2-3-shifts around 30mph.
(There's a 3.91 gearratio in the rearaxle)
Some more info;
- With light throttle, the 2-3 upshifts are very late.
- With moderate/firm throttle, 2-3 upshift timing feels correct, right on time.
- Shifts themselves are nice and crisp.
- 3-2 Kickdown always seems to work good and as expected.
- Reverse gear engagement always is very soft.
My gut feeling says there's leakage somewhere in the transmission and internal oilpressure needs to come up to a certain pressure or flow before the 2-3 shift is initiated.
I don't mind getting into the transmission or valvebody to fix this issue, but I do like to know what to fix so the problem is actually cured after that.
I hate just throwing new parts at some issue, but I'm thinking of getting either or both these items (unless someone here can pinpoint the issue to one part);
- #518RED16. Sonnax, Dodge 16% Oversize Intermediate Super Servo.
