Hey everyone, I have been noticing a problem, which is really beginning to bother me on my '83 733i/A. My 3spd automatic transmission (ZF3HP22), is shifting hard in second, somewhat like a thunk sound his heard and felt through the car, it sounds like it is heard from the differential. It, however, does not do this in the shift to third though. But after shifting to each gear, there is a noticed vibration while still accelerating, until you stop accelerating, and level to a cruising speed, then you can begin accelerating again with out the vibration. I have 306032kms on the car with the tranny being rebuilt by the previous owner at 221730kms. I have access to a lift and all sorts of tools in my mechanics class at school, permitting that this can be an easy fix by myself. If not, should I have the tranny fluid/filter changed, the tranny rebuilt? a new tranny? maybe upgrade to a 4spd? new Ujoint?

Also my differential is leaking a bit(related to tranny problem?!) should I put a new seal at the end of driveshaft, entering the diff?

Also I'm losing coolant, I don't have a blown head gasket, there is no emulsified oil, I am geussing that there is an external coolant leak, the coolant collects and drips off the tranny, a cracked hose? Do hoses run close to the tranny underneath the engine?

And lastly my car has begun to burn a little oil, should I rebuild the head and replace the valve seats, valves, springs, rockers, and maybe put in a new cam? Also rebuild the bottom end?
I need ideas and help with these problems, my '81 728i's drivtrain was virtually maintenance-free! and now I get a hold of this 733i/A, and I'm in a whole mess of trouble!!
I tried to make each description as detailed as possible. Hopefully one of you would have unfortunately encountered some of these problems and know how to fix them, any help is greatly apprechiated!!!!!!!!! hopefully I canfix them myself.
