Do I have to remove the exhaust cross over pipe to remove transmission? 1998 4x4 4.0 with automatic trans. Also any step by step instructions how to remove tranny?

 

I believe you do. I didnt, but I had a body lift which I believe gave me just enough room.

You will need to do the following...

remove the starter
find each bolt from the torque converter through that starter hole, there are 4, so you will need to turn the crank by hand with a wrench. until you remove each nut.
remove driveshafts
remove the transfer case
remove electrical
remove tail housing bolts
remove crossmember
for the most part that should get it out, if not close. that should help some.

 

^agree, my repair manual said to remove the exhaust but since i had a body lift as well i didnt need to at all. It may even be easier for you to unbolt the cab and lift it up a little if the manifold bolts are completely shot

 

can of pb blast will be your best friend

 

Yes, remove y pipe. I broke 3out of 4 when I did it first, try to work them back and forth. If not, break out the oxyacetylene and be prepared for about 3 hrs of fun removing studs!

 

Thanks for the advice. My son was driving the truck and the rear u-joint came apart dropping the rear drive shaft and cracking the transmission and leaking fluid all over. So I started to tackle this project, but I may have bit off more than care to right now, its been a pita so far. But on the bright side I picked up a new style (alum) drive shaft from the salvage yard for $50.00.

 

that aint a bad price for an aluminum driveshaft
