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?

'81 300SD Turbo Diesel - Trans slow in engaging reverse.

I have an '81, 300SD, that sat in a field for 2 years due to leaking engine oil cooler lines. Replaced lines, checked all fluids, started and ran, and then took it for first test drive. Noticed it was slow going into reverse. Have zero (0) power to power-brake booster. Figured vacuum pump needs to be either replaced or rebuilt. As I checked the transmission fluid, with the engine running and the transmission in park, when I checked the fluid it seems to be over-full. Previous owner was adding Dextron/Mercon trans fluid. As I put it into reverse it is taking longer and longer each time for the reverse to engage. Are the above my problems, ie: vacuum, wrong trans fluid, improper checking technique, or is the transmission going south?

85 300 CDT no heat

Hi I have a 1985 300 CD turbo and I have no heat. So far I have taken apart the control panel and cleaned all the switches and re soldered any suspect connections, I also fixed the aux water pump so I know that is working now and I bypassed the mono valve so the water will flow through the core, but still have no heat. the fan works and I have air coming out of the defrost and outer vents, but no air at the floor. Can anyone point me in the right direction as to what is wrong with this?

Thanks,
Phil

84 300TD wagon transmission leak

I have a transmission leak. It seem to mainly be leaking out of the driver side (opposite the drain plug) of the pan...mainly from the center bolt back toward the rear (toward the rear of the car) bolt. It almost looks as if it's leaking out between the pan, the gasket and the seal between the gasket and tranny. I've replace the filter, the gasket and the pan.

Hopefully this wordy description can lead somebody to help me out. Thanks in advance.
