turbo removal without dropping trans??

Alright I ran into a guy I know at the pub we both have D-maxs so we like to talk about what we are doing or planning to do with them. He tells me hes helping his friend who has a lly same as me do head gaskets on his truck. He tells me that they are dropping the trans so that they can get to 2 bolts on the back of the turbo so they can remove it and that there is no way to remove the turbo without dropping the trans. I called bullshit because I can't believe that you would have to drop the trans to change a turbo if you needed to. My guess either they don't know enough about what they are doing or don't have the right tool. Could someone on here tell me if i'm right or wrong thanks much. These guys are also on duramax forum so maybe your answers will help them if they see this post.

There is no need to pull the trans to remove the turbo. Every fastener can be had from the wheel wells and from up top. Also there is no need to remove the turbo to do the head gaskets.

X2... I literally just changed my turbo on the weekend. A bit of a pain but definately doable with the right tools and patience.

pulling the tranny will about double the time i takes to change the turbo. a topside creeper would be the shit, but i just layed ontop of the motor. deep 12 pt 12mm socket with a long articulating ratchet will do the job.

You'd be better off lifting the cab than dropping the transmission IMHO, but definitely not necessary by any means.

You do not have to drop the tranny, it would consume more time to do so... Turbo comes out through the hood, just did it on a lbz this weekend, only tough spot was pulling the turbo out because the lbz air conditioner freyon pipe was smaller than an lly

oh thanks to you all so happy i'm not going completely insane. Just being crazy is enough for me. yup I hope they see this thread then. I in no way could ever see having to pull the trans to get the turbo off to do the head gaskets. One of you even said they dont even need to take the turbo off to get heads off. I would think it would be easier with it out but I understand what your saying just disconect the manifolds. wait??? wont you have to take turbo off to take intake manifold off?? sorry thought typing. Thanks again everyone.

No need to take the turbo off. I left the exhaust manifolds and intake runners on the heads and got them off without a problem. Unbolted the y-bridge from the drivers side runner but left it attached to the pass. side and took them off that way.
