Depends on the working conditions. In a semi-heated shop or small garage with lights, and flat level floor, some jack stands and a floor jack, it's not that bad. Taking out the engine and trans as a unit is quite easy. ( but if doing just the trans, then just take that off and leave the engine in place - you need at least a bottle jack also ) On the other hand, if it's 'all outdoors', or worse, outdoors and not even on flat level pavement, then yes, that's a real tough thing all right ! For some odd reason I always liked to drink a lot of coffee and do it in the middle of the night ! no distractions then. Sounds to me that given the time of the year, and I gather not excellent working conditions, and the engine is working all right, like has half decent compression and no coolant leaks, then just to the trans for now. s. -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of David Kao Sent: Thursday, December 13, 2007 6:42 PM To: vanagon@GERRY.VANAGON.COM Subject: Re: AMC Cylinder Head Question I did not mention, my 84 Vanagon broke its transmission last week. I heard a loud snap from the rear, like breaking an axle and I lost power to move forward. It was in first gear trying to move into another street on a right turn. I can still shift back and forth to every gear including reverse. But As soon as I try to let go the clutch pedal I can hear noise from the transmission. So the transmission is toast. I have one used cheap spare that I can replace. But once the engine and the transmission is dropped I have a decision to make between a real quality rebuild or a cheap one by myself. I do not need to do anything with the engine if I want to go the cheap route. If I want a quality one then it's a lot of money and the engine should take the opportunity to be done as well. It's not fun to do something like this in winter time. David --- David Kao <dtkao0205@YAHOO.COM> wrote: > Thanks, Mike and Bob.
