Jack the car pretty high and support from drip edge (factory jacking location in front along door sill) I go to the limit of my jack.

Easy

depends, if you have a tranny for them to install then less, but if you have them rebuild and install it will be more

with your own tranny prolly 800-1200, depending on what kind of shop

they rebuild your tranny and install: prolly 1500-2000

Im just guessing here, but its more like from what i heard kinda guess's.

call a few places and see what they say

i just got my new transmission.. i will use this write up as a guide in removing my old transmission and replacing it with the new one. Thanks for sharing this!

My only concern, maybe I missed it, but how do you lift the car up high enough to slide the trans out from under the car? I'm used to doing this on a lift, but not on the floor.

LOL

could you say 2 mechanically inclined noobs with all the right tools could pull this off in less than say, 6 hours?

bump

Bump?

GT..That's gonna be a tight deadline. I can zip one out myself in about 6 if I'm cruisin.

WOTGTP, Intrigue98 and myself did one in about 3 hours one night. that was hustling though.

Well this will be interesting

It's easy. One other trick. If you don't have enough extension for the backwards bolt. lower the ps pump as mentioned, then use about 12" extension under the exhaust manifold. You can do it that way as well.

Okay well the facility closes at six so I guess i'll see how much I can get done now and finish pulling it later

I guess I didn't realize how much had to come off to pull a transmission

I added some pictures of how high I go. Pretty much the limit of your jack. Depending on how you raise and lower the transmission will matter. I have an ATV jack that I use to lift/lower the trans and it works great. Takes up a few extra inches though.

its should be very close if not all the same really. its just a matter of unbolting it all and un hooking the lines and wires and shift linkage and so on.
