So today has not gone well at all. This is the pinnacle of the mountain of chit that I have had land on me today.
Coming home, going down the interstate from a city 40 miles away, I was cruising at 75mph. All of a sudden, OD kicked out and back in. It continued to do this for the next 15 miles where I got off. Check fluids, 1 qt low while still in the safe area. Checked in neutral. I noticed the voltage would fluctuate between the 2 normal lines. It sometimes kicked out when hitting a bump. Didn't matter the throttle position or speed, it would go in and out at random. Sometimes I could pull a hill accelerating, sometimes I would go 45mph for 2-3 miles. I think the AC was also doing this but it is cool here and I got cold quick.
I get home, add a quart of fluid so it was at the full mark. I go for a quick drive. I start accelerating from 30mph to 60mph. It shifts like normal and holds 60 for a quarter mile. Then it goes out completely for the 6-7 mile ride home.
Fluid is a mix of ATF and tractor fluid. I did notice on the couple hills I was able to accelerate, OD felt weaker than normal. Fluid looked ok but it is dusk here and I don't trust my eyes in dim light.
Also in its last 150k miles, it has not had a rebuild. I have had it for 30k miles, the owner before had it for 120k miles. The owner before him never mentioned a rebuild.
PCM, Crank sensor? OD gone? I will get my fluke from work and OHM out what I can.
