Hello, I've been thinking about doing my timing chain for a while now, and have decided to lift the engine out to do that and maybe a few other things. I heard a lot about how the gears and guides wear as much as the chain does. Some people have told me that replacing the transmission is not that difficult once the engine is out (and neither is engine removal!). Would it be worth a shot if I managed to obtain a manual parts car of the same engine/transmission design as my car , or is there just too much modification involved in the conversion. I've got a long vacation coming up so I'm trying to plan out my quality time with the Saab. My car is a 1991 9000 CD turbo AUTOMATIC . As to my mechanical skill, I've replaced alternators, valve cover gaskets, rear shocks, thermostat, rebuilt the rear calipers, fit new tie rod ends, and of coarse all of the usual maintence related work, on various cars. But never removed an engine! Any advice appreciated!
