torque/power split on a 4EAT

[Danteandsoob]

Does anyone know what the ratio is for a 1993 legacy L 4EAT is in overdrive, 1st , 2nd, and 3rd? likes, threads or specs are greatly appreciated.

If I remember correctly your Subaru Bible actually tells you (user manual) If you don't have one pm me and I will get you the specs..

It is constantly varying depending on driving conditions, but if you're cruising down the highway it'll be about 90/10. The most it could ever be is 50/50. The amount of rear drive/lockup will primarily depend on acceleration/throttle position and front & rear wheel speed differences.

So what does the ratio look like in 1st and 2nd manual gears on an automatic? That guy never got back to me on what the specs were.

50:50 split in 1st and 2nd when you have the gear lever in those positions.

Awesome, thanks so much.

If you wish to verify, many multimeters have a duty cycle function. This can be used to monitor the wire that goes to the AWD solenoid (Duty cycle C?). The wiring diagram will show the wire color and position. The trans ECU is right above your left knee, so tapping the meter into the wires should be pretty easy.

100% duty cycle = 50/50 torque split
50% duty cycle = 75/25
20% duty cycle= 90/10
etc...
