It won't go
seriously, though...
put it through it's paces. It should do all of the following:
* engage promptly at idle.
* move off with minimal throttle and shift up, almost imperceptibly, so that
it's in 4th by the time you're doing 30-35. watch the rev counter, it'll
drop 2-300 revs going into 4th.
* move off briskly if you floor it, and hold first gear till the revs hit at
least 4K. Be prepared for upshifts at full chat to be a bit violent...
* kick down from 4th to 3rd at 50 with not very much boot applied.
* kick down to 2nd at 50 with lots of boot appplied.
* go back down the box as you come to a halt. 2-1 is when almost
stationary.
* select any gear (3, 2, 1) when the lever is put into that position, pretty
much immediately, certainly within 2 seconds, unless you're above the
maximum speed for that gear, and thereafter not change up again.
* go into 4th-lockup at about 50 mph, under fairly light throttle. revs drop
about 2-300 again. Once in lockup, it'll only kick down from that to third,
and if you release the pedal, it should go straight back to 4th-lockup, with
an attendant revs-drop of 5-600.
BTW, I don't recommend you try for the 3rd gear kickdown threshold, that's
at about 85, ISTR.
It shouldn't do any of the following:
* make undue noises in any gear
* take a long time to engage gear from rest. normally about 1s in my
experience
* "slur" when changing up - as if on a manual you were slipping the clutch.
* change up violently/jerkily under light-to-moderate throttle.
* "hang" in first gear under light-to-moderate throttle - upchanges should
be around the 1500-2000 rev mark under gentle acceleration.
* make a bloody great clang going from first to reverse when stopped -
though this is rarely a box fault, it indicates mucho wear somewhere in the
rest of the transmission.
You can also do a stall test:
warm up engine and box to normal temp. Engage D, stand hard on the brakes
and floor the throttle. IIRC revs should stabilise at about 1800. Don't do
this for more than about 5 seconds. Low revs most often mean an
underpowered engine, high revs mean a box fault, either converter or one of
the clutches, time to walk.
aha: shift speeds for a 3.9:
light throttle: gear-gear @ mph (range)
1-2 @ 9-10 2-3 @ 18-22 3-4 @ 26-30
part throttle:
2-1 @ 10-12 3-2 @ 29-37 4-3 @ 47-54
full throttle: ("feel" for the kickdown position. FT is just before the
kickdown cam engages, which you can feel on the accelerator pedal if it's
properly adjusted - about the last 1/2"-1" of pedal travel before it hits
the floor)
1-2 @ 29-34 2-3 @ 55-60 3-4 @ 74-80 3-2 @ 40-46 4-3 @ 61-67
Kickdown: (pedal mashed...
)
1-2 @ 34-40 2-3 @ 60-63 2-1 @ 27-34 3-2 @ 57-62 4-3 @ 84-92
Lockup in: 51-54 Lockup out: (decelerating lifted-off, hard to spot) 49-52
