i have to pull the tranny on my 1999 7.3L powerstroke 4x4 this weekend to replace the torque converter. Now i consider myself pretty mechanically inclined, i worked at an auto shop all through high school and have pulled many transmissions. But all of those were done on a 2 post lift. I have to do this job on my back in the driveway. Now i have pulled the tranny on my 02 Z28 3 or 4 times already but i know that is nothing compared to the monster in this truck. So i am just wondering if anyone has a step by step writeup on this or if anyone can give me any pointers other than the obvious. Thanks!

thank you for the information! Every little bit helps!

WOW Neal!....thank God for copy and paste ehh?

Nut

 

You ain't a jokin', Nut!

 

I quickly glanced at those instructions and would like to mention that I didn't pull the transfer case off when I pulled my six speed. If all you are doing is a torque converter, I would leave it in place and simply drop the driveline and remove the rear crossmember.
PLEASE chain that transmission to the jack!!! They are too heavy to control if they get off balance.

 

thanks guys!! anyone else?

 

Yeah I agree with Kwik, I stopped what I was doing and rented a jack for 35 instead of killing myself. This thing is uncontrollable at best.

 

I just got done pulling mine and we were gonna just use a floor jack. Last minute found a tranny jack, thank god, I had no idea how heavy that thing was. Mine too is early 99 and we did not take the transfer case off either.

Hey Kwik, my pilot bearing was bad and it scored my shaft a little. Hoping that a kevlar bushing will take care of that.

 

thanks for all the help! I am definately using a tranny jack from the auto shop i worked at! No way i would use a regular floor jack!!

 

I picked up a tranny jack from Harbor Freight for 70 bucks a few weeks ago. Made pulling and installing the trans in my F150 a breeze.


I then proceeded to kick myself in the *** for not buying one 15 years ago.......
