AT OD flashing at idle

[fixkick]

when fixing cars, or asking for help?
it's wise to state all things on the car that are missing, or not working right.
the engine and the TCM,
both must know road speed, (that means not bouncing either)
if not the ENGINE power will be lacking
and the transmission will not shift correctly
same in 1996 and 2015


i might add.
I had to buy 3 clusters and mix the parts in all 3 to get one good cluster.
on my last car. (tracker)
one test i did (after buying them all on fleabay)
is to bench test it.

lamps ok, good
tacho, using my pulse generator
then fuel, and coolant temp.
last was the speed.

i took a variable speed drill motor
and on old speedo cable cut down to 6inches.
chucked up the cable, with round end.
and inserted the square in , in to the speedo fitting.
i switched the drill to reverse and slow speed.
i turn it on.
the needle fails to move, (scrap that meter)
next cluster. ok it moves, but the needle bounces as it moves. trash can 2.
last it moves and dont bounce and makes NO NOISE. (ear to casing)
good meter.
and odometer works
and vss clicks.

working on old cars is like that, mixing parts to get one good speedo head.
the good head had a bad tachometer, so i swapped the dead , to the good speed head.

some of these ECU , go to limphome , when VSS dies, completely , a bad place to be...
