1uzfe automatic not changing gear when in d but wil change when manualy done

[v8hiace]

i have a 1uzfe from a crown in my hiace have wiring up the automatic ecu n by check very wire in since to be working.

but when i put the gear stick in d feel like its taking off in third gear and wil not change gears

Do you have power to the solenoids?

sideshow does a box to fix this
i believe it has to do with the number of pulses from the speed senser
i had one at work doing this in a hilux with a crown ecu

If it works when manually shifting, then its a wiring issue.
Most likely you've missed a +12V wire somewhere.

FYI, even when shifting manually you don't get all the gears. L is 1st, 2 is Drive, and D is Overdrive - ie, you don't have 2nd gear.
Do this for too long, and you'll damage the box.

got power to all solenoids
side show was saying something about a speed module
Niel have u got a pic of that box

i dont sorry, but it was just a black box about 75mm X 40mm X 20mm with 4 (? i think) wires out of it.

neg
from speed sensor
to crown ecu

its a while since i did it but it fixed the problem

As long as you have 1 speed sensor, it will still work fine.
There is normally one from the dash to the ecu, just a single wire.

Wire that up, and it should work fine.

yeh thats all wiring up
the crown electric dash is all working and the computer his the two speed sensor wired to the ecu and still no shift

Mine did this when i blew the fuse for the 12v ignition feed to the Auto ECU.
