What did you do with your GMT400 today...or yesterday....

[Big T]

That's one of the things he mentioned

This sounds like a 4L60e thing?

I don't know, seems like a lot of shit that's goes into a transfer case rebuild. More than just a chain. Probably special tools, etc. and that does not even address the encoder motor for 4 Low.

A lot more in there than the old NP203.
Might be good to have the rebuilder handle that one.

I agree with Will about the Zero labor cost for the T-case when doing the transmission R&R. It's kind of a no-brainer unless it worked out that when they were doing the transmission, you did the transfer case if you wanted to. It's not always about the cost, just nice to get it done asap.
Big T, I would go ahead exactly like you planned.
The reason I'm pulling mine is because I have a lift and a transmission jack and there's a few other things to do while it's on the lift

Here’s a decent video showing the tear down. If ya figure it’s too much- then have them do it.

So which transmission do I choose?:

HEAVY DUTY UTILITY (bullripper.com)

EXTREME DUTY TOW MATRIX (bullripper.com)

 

[Will L.]

Yeah- 246 SHOULD have the full kit done. And it is about the most complex one so I wasn’t figuring on that for ya.
But what I am saying is a lot of places ONLY do the little plastic pieces on the fork and a new chain then send it out calling it a rebuild. Remember they make better profit by less new parts used.

Thats why I like to have MINE rebuilt wether I do it or someone else.
If you have a highly respected shop near you to do it- great! have them do it all.

Many shops just r&r whole units and get “reman” units at a set price. Those are usually the ones that come with a box of regret built in.

Those seem like some well built units.

The place has been in business for decades. Outstanding reviews. Definitely not cheap.

Sounds like either one would get the job done but it's an extra grand for the Matrix. I'm assuming yours is stock now with how many miles on it?

Thats why they are still in business. They charge enough to cover costs and labor.

232K miles. I do tow a Conch 27 saltwater boat which probably weighs in at a max of 9,000 lbs. But I'm not doing this daily.

 

[Grisley1958]

I think that was an issue clear back on the 700R4 which was the predecessor to the 4L60e. Not sure if it was an issue on the 4l80e

You got pretty good life out of that one!

This is the place my mechanic recommended for the transmission. Need to call them during the week about transfer cases They show rebuild kits, but not reman transfer cases, though I know they do them. Last time I was pricing a quality reman transfer case, it was around $1,000+.

I have Energy Suspension Urethane engine and transmission mounts ordered as they will be replaced while this work is being done.

If you are not adding a big power bump, not towing a lot more than you did before, etc. I ask what is it you need to upgrade for? What is your roi?

Got it. I will do the HD.

 

[ak diesel driver]

Roi?

 

[Big T]

Roi?

Return On Investment = ROI. Had to clarify that as it is a rarity coming from Will L.

 

[Big T]

Have new ball joints arriving tomorrow. The existing ball joints were fine, but while I’m in there I’ll go with new MOOG ball joints. Pulled the steering knuckle as I need to ream them for the ES409R tie rods.



While removing the passenger side CV axle, the cracked inner boot gave it up. I have the replacement and will add that to the list today.

 

[dbrannon79]

be weary of moog! their quality has diminished greatly over the years. I had replaced all the upper and lower control arm assemblies on my truck. had one lower ball joint lock up on me and ended up just replacing the joint with a delco one because I didn't want to go through removing the control arm and dealing with the coil spring again.
