how hard to change tranny mounts?

[delta9blazer]

my truck just got lifted 4", and 35's. now i notice my tranny jumping just a bit if i leave a stop moderately hard. you can see it move under load if you look.
is this something that i'll be able to do in my driveway? my neighbor is a back-yard mechanic from way back, and i ain't asceered to get my hands greasy. it seems that it would be loosening a few bolts, supporting the tranny while the old rubber crap is removed and new mounts inserted, then lower and tighten.
or am i simplifying it?

thanks!

Block the wheels
Set E- brake
Put truck in nuetral
Use a floor jack with a small 2x4 or 2x? to raise the tranny, or
If you have a big floor jack, raise it at the xfer case.
DO NOT raise it from the rear of the tranny! @ the rear seal
Unbolt old mount
Bolt new mount in
Lower tranny back down and tighten bolts
Put truck back in Park and remove blocks
Go inside to the refrigerator and get a beer

Wait a sec,
Your tranny is jumping? Did you shim the rear end when you lifted it? If not it may be binding. You can lower your xfer case to help some.

and how is the lowering part accomplished? i don't mean to sound like an idiot, but i'm kind of an idiot.

oh, and the mounts are visibly deteriorated. there may be some binding, but the mounts need to be swapped out, regardless.

You need to raise the tranny up with a jack to get the old mount out. After you bolt the new mount in, you will have to lower the tranny back down, then bolt it to the crossmember.

Do a search on this site to find out how to lower the tranny. It takes to long to explane it. Just click on the search tab at the top of the page and type in "lowering tranny" or "lowering tranfer case" or "driveshaft angles". Hope that helped.
