Yes, it is definitely a challenge to pull a tranny from a used car. You’ve got a some advantages though. There’s probably a lot of stuff already removed from the car at the pick and pull, so less preliminaries to do before the actual trans removal. And the car is already up in the air a bit more than you’d be able to achieve in your driveway. And its a Camry, so finding documentation how to do it won’t be much trouble, and its probably going to come out without too much trouble anyway, just b/c that’s the way Toyota econo-boxes are designed; i.e. simple to service. At least Toyota’s in the 1980’s.
Suggest to visit the local pick n pull for a look see. While there you can see what other folks are removing. If someone is removing a transmission, when they’re taking a break ask for some tips. Usually the customers there are pretty friendly and willing to offer advice as long as you don’t interrupt them in the middle of the job they are trying to do.
One bit of advice: If you’ve never done a job like this yourself involving persuading heavy objects to do what you want – never replaced a clutch, never replaced a timing belt on a transverse engine involving the front motor mount, never removed the third member from a rear differential – you’ll probably need someone to help you who has done something like that before. One more thing: There’s a photo somewhere on this web site showing Tom wrestling a transmission from a car. Take a look at that photo. That’s going to be you, if you decide to do this. You sure you want it to be you? … lol …
