Is there something specifically hard about removing an auto tranny, especially on these trucks? I could see removing a FWD auto tranny being a PITA.
I haven't pulled many transmissions but the one I helped pull on a vette, took us maybe an hour.
Disconnect the drive shaft, un plug all connectors/sensors, disconnect all the linkage, remove all transmission lines, un bolt the all fasteners holding the tranny and remove.
Or are there clearance issues? Does the TC have to be removed from the tranny first?
Like I said, haven't done it on a 4R before but on face value, it doesn't seem like rocket science.
No, it shouldn't be that hard, but like anything you haven't done at all or many times, it's going to take more time than someone who's done it a bunch of times. I have some experience pulling manual transmissions but no experience with an automatic. There's the fluid lines you'll have to disconnect and the extra step of unbolting the flex plate via the bell housing access plate but it shouldn't be that much harder than a manual. Plus, we're doing this on our backs and not with a lift and that's always harder.
I'm guessing it would be advisable to disconnect the transfer case first since it's got to come apart from the old transmission anyway, and then you'll have an overall lighter unit to manipulate and separate from the engine. I haven't looked at what the FSM suggests but this will probably be the route we'll choose.
Supposedly, just like it is on other transmissions, the upper bell housing bolts are the hardest to remove because of the clearance problems. I've read that somebody used a very long extension with a swivel so he could use his impact gun to get them off. This is what I plan on trying as well.
Somebody said they could have this job done in 4 hours. I know my capabilities as a DIY mechanic and I know there's no way we'll come anywhere close to this. I'm a competent mechanic but I'm not quick by any standard. So, I'm assuming this will be an all-day affair for us. Sean and I also take longer because we're always video documenting the repair or mod and it adds quite a bit of time messing around with lighting, reshooting clips, etc.
