Inherated a trooper I dont know why it was parked no one to ask? So I picked it up, sat for three years, I put in a batt. Started right up. I noticed after I moved the trooper there was a oil spot where there was a leak. I checked the oil it was fine clean. So while it is at idle I checked the tranny fliud empty. So I drive it to my house there is a weird smell and a lil smoke coming from under the drivers door when I step out. The temp gadge was not even 1/4 way to operation temp. Oil perssure gadge reads 60 when cold then around 30 when warmed up and goes up when I give it gas. Ive tryed to get the truck to overheat by letting it idle in my driveway for a while but it doesnt get hot. But there is a lil smoke coming from somewhere by the tranny. I dont know if it is just stuff burning off that has got under there over the years? Or the tranny or the cat? There is a smell but not like rotten eggs or sulfer. It could be old oil and grime burning off I dont know. Please help any feed back on this is greatly appreated

The transmission is raise the cooling temp slightly if it uses a radiator oil cooler, but not enough to affect engine temp. The smell may well be just oil on the exhaust burning off, inspect the exhaust and transmission for leaks, after sitting for a long time seals do go hard and can start to leak.

Is there something I should put in the tranny that will rejuvinate those seals?

No, the additives are petroleum based and only cause the seals to swell up they seal for a short time but they will fail again, and this will affect good seals as well, if you have a leaking seal, it should be replaced.

Drain tank and replace filter, add premium fuel and you can use a small amount of methylated spirits 200ml say as this will help disperse any moisture in the system and it is harmless to the fuel system.
