Before anyone start yelling for me to get the manuals... I already have the haynes manual and its about as good as a $5 hooker.
What I need is advice, tips, trick and whatnot to help me remove my tranny from the engine WITHOUT taking the engine out of the car. I really, really, do not want to remove the engine from the block.
So far, I have the half-shaft removed from the tranny and most of the cross bar from underneath of the car off, except I can't take it off because of the upper cross-bar that runs from driverside to passengerside of the car. Please any advice on this would be appreciated.
p.s. The haynes manual said to remove the tranny and block together and I am trying to avoid that. Unless it is impossible then fine, I'll do it.
Oh and the vehicle is a '91 (I think) Corolla with the 4afe engine.
I don't think you have to remove the engine and tranny together just to get at the transmission, that's usually advised when you need to remove the motor itself. You should be able to get the transmission out while leaving the motor in there.
The Toyota Service Manual says that an automatic transmission should be removed by removing the engine with the transmission attached. A manual transmission should be removed from below by taking off quite a list of things. This include both the cross member and the center member, the exhaust pipe where it attaches to the exhaust manifold, the starter and the transmission center mount from the center member and the transmission front mount from the center member.
Take the cross member with the attached control arms lose from the whee assemblies. Some of the bolts that go through the middle of the cross member into the center member have a plastic cover over them than pops off. Some bolts go into nuts that are welded inside the hollow center member and it is easy to pull these nuts loose when you take bolts out. The bolts that hold the center member to the front of the car are easy to strip. (I think they get somewhat stripped when the car is put together at the factory.)
You should consult the genuine Toyota Service Manual when doing a big job like this. For example, the torques on the various suspension bolts vary betwen 45 and 152 ft libs. It would be best to have these torques right when you put things back together.
erm... Nothing against the Toyota Service manual, but you do realize that the book, itself, is well over $100? I think closer to $150. If I was gonna dish that kind of money out for a one time transmission change, I might as well take it to a machanic and have them do it. I already ask how long it would take to do the job by a qaulify machnic and was told 3 hours. At $50 an hour, it would be the price of the book without the headach.
The whole reason for doing it myself, with various members help, is that I am still a highschool student with a limited income and this is gonna be a daily driver with very little in term of machnical mods. I like to keep it stock as possible.
Now, please, what I really like to know is: is it possible to remove the auto-tranny from the engine WITHOUT remove the engine and tranny from the car. Not what is recommended but what is possible. And if it is possible, has anyone done it and if they have any tips, trick, and whatnot that can make the experience a little easier on a noob doing it for the first time.
You can get used service manuals for the on ebay or on abe.com for about $45. The '90,'91,'92 manuals would all help you with your car. Some people sell what looks like copies (probably illegal) of the manual on cd for about $10. I haven't examined such cds. I agree that having a shop do it the job would be costly. In fact, it would probably cost you more than $100 to have them change the AT. I understand that you seem to be in a hurry. I,myself, have not tried to remove the AT from underneath. Let anyone who has done this, speak up!
My suggestion is to visualize what is going to happen after you remove all the stuff required for the manual transmission. If you take all that off ( including the center member and cross member). Is it going to come out? I have a 4AFE with the AT taken off of it sitting in my garage (as do several other forum members, I suspect). So we can tell you about what bolts are where.
Wow...$50 an hour is pretty damn cheap. Alldatas procedure says you have to drop the engine and trans together. Mitchell says the trans can be taken out seperatly as long as you have a way to support the engine, but theyre removal procedure is not very descriptive. I dont see why you shouldnt be able to take the trans out by itself, as it can be done in almost every car.
