1984 300SD - Transmission slippage

I had the rear end on jack stands and the front wheels on the ground while I was doing rear suspension work (shocks, springs, cv axles). I kept getting interrupted and left the car in that position for about 3 - 4 weeks before I finished and now the transmission feels like it's slipping. I've never had transmission problems and I changed the fluid and filter a few months ago. No fluid leaked while the car was jacked. Was it a bad idea to leave the car in that position for an extended period of time? I'm not sure how to troubleshoot this, any suggestions? Thanks.

86 300 sdl's tranny has problems...

At any altitude above 3000 feet my car's transmission shifts roughly, sometimes refuses to get out of second and when it does, will not go into fourth. I discovered this yesterday while on a trip up to Lake Tahoe- did not make for a pleasant experience as one might imagine. Is there a Barometric switch anywhere in the system that might have gone erk, or is there some other problem that might be the culprit? The Trans shifts normally here in the valley, if that's a help.

lpg convertions

Has anyone played with lpg or natural gas conversions on the fuel injected engines? these gas cars could use a little help in the mpg dept.
Being naturally fuel injected should make the conversion simpler. But the danger of blowing up a perfectly good engine has its drawbacks.
Back in the 80's it was a fairly common conversion, but I haven't heard much about it lately.
Now you hear PikensPlanCNG.
Sounds promising, but is it practical?

84 300SD transmission governor screens

I would like to check and clean the governor screens in my 84 300SD transmission, but have no idea how to go about doing it. I think they can be accessed near the filter, but don't know anything about transmissions. Any suggestions? Are there any books or manuals available to teach me how these transmissions work and how they can be serviced and repaired?

Thanks for your help - Steven

85 300SD Aux Fan will not turn on when pressure is high

I have been experiencing a couple of problems with the AC. One was the compressor clutch "cooked itself" resulting in it being replaced. After it was replaced I noticed the aux fan was not ever coming on and the clutch still has moments where it is not completely engaging and is partially engaged resulting in it heating up. I have troubleshot the aux fan down to the resistor used for a slower aux fan speed. It appears to be open and should be replaced. Could the failing of the aux fan cause the slipping of the clutch and how difficult is it to replace the resistor?

Thanks
