My output shaft grenaded a while back, been almost a year. My truck has been up on jackstands with no tranny the whole time. I bolted the new trans in saturday and had to stop there. The tailhousing is supported by a jack for the moment. All the bolts have been sitting in a pile this whole time and now I have to remember where they go. What I can't remember is whether I put the exhuast back in first before the crossmember, or can I bolt the crossmember and tranny mount in before the exhuast?

extended cab, 2WD factory exhuast etc. 4l60e.

thank you

 

Y pipe goes in 1st then the crossmember
7 bolts hold the tranny to the block 5 are stud type with 3 that have nuts on them to hold: the dip stick, fuel lines, vent hose.
3 short converter bolts.
2 starter bolts.
6 nuts to hold the Y pipe to the manifolds.
1 nut to hole the tranny to the cross member
4 hole the crossmember to the frame
2 at the exhaust flange from the y pipe to the rest of the exhaust.

 

I took the Ypipe and whole assembly out as one piece, so I would have to bolt that up first, then put the crossmember and tranny mount up.

Thank you

 

I've removed my factory y-pipe a few times without touching the trans crossmember, so I believe that you can do it in either order, although it would probably be easiest to put the y-pipe up first, then the crossmember.
