    It could be a transmission issue then. I'm not a transmission guy, but I'd start out by pulling the pan and replacing the screen/strainer assy. I'd also check for metallic particles in the fluid and on the pan magnets. If the fluid smells burnt and/or there's a lot of metal flakes in the pan, then you may need to visit a transmission specialist.

    Okay I'm going to pull the pan and replace the strainer assy. Is it 4WD specific? Is this the right kit? https://www.partsgeek.com/gbproducts...+Kit+1987+1985

    Thanks Tim!

    Yes, that's it. That one fits all years and all models of US vans with auto transmissions. More details on this job can be found in THIS THREAD starting on post #14.

    Update, transmission seems to be performing much better after changing the fluid and filter. It shifts more smoothly at the usual RPMs again and engages at lower RPMs in reverse like it used to. The true test will be to see how it performs in the cold.

    Thanks again for your time and help Tim!
