Aod will not work in any gear. I am going to remove from car and was looking for advice on what I should look for first. The trans is a level 10 with about 3000 miles on it. The car set for about 3 years. I replaced the engine and started the car. I ran the trans through the gears and checked the fluid/level. The car ran through the gears then slowed for a curve then reapplied the gas and all the engine did was rev. The trans will do nothing in any gears.( load the engine, turn the drive shaft). The fluid looks like new and is not burnt.
