I've never actually had to lower the transmission, or even raise the engine much before in all the years of doing work on my vehicle. I am just starting to replace my transmission lines, and really have just one basic question. As far as lowering the transmission, raising the engine, moving the transmission to the side, is there ever any kind of alignment or damage I can cause? I know there is a lot of weight there and to be careful. I'm asking because I've also done work on rav4s, and you have to be careful with the driveshaft not to let it "bend" over 20 degrees or you can damage it. That's kind of what I'm looking for, is there anything to be careful of in regards to damaging the vehicle (not me lol) For example, can I just put a jack under the tranny, remove the cross member and drop it down as much as it wants to go? I wouldn't do this without studying things that are dropping down and being esposed to stress as well, but I think you get the idea of what I'm asking.
