What did you do to your NBS GMT800 Tahoe/Yukon Today?

[SnowDrifter]

Gotta get those idle volts up. Maybe an alt OD pulley is in order.

That Trucool 40k and melling oil pump... Jealous

For the trans cooler did you bypass your radiator? or are you running in line like the oem setup?

I am running this cooler:

Which should be fairly close in performance to the 40k theoretically, but i still get trans temps in the 190* range (without towing or hooning) with the rad bypassed. I have it oriented with the in/out lines down just like the OEM setup. M

Kept radiator pass through

Voltage is fine. My rig has that weird smart charge thing. Dipped down to 13v when the current clamp read the battery wasn't accepting any more juice.

With that said, I would just toss a proper high output in there if I needed more

OIC. A lot of "high output" alternators are just stock style alts with OD pulleys.

Seen this today . Truck was super clean. Thought it was nicely modded . Just needs some aggressive tires. Next time I’ll find out who owns it. They work in the area View attachment 228024View attachment 228023

I hate those cheapo bull bars. They are just damage multipliers, and they dont look good imho. Otherwise yes nice rig.

Really liking how these minor mods are holding up

Was the oil pump a tricky install? Looks like you've got plenty of pressure! 50psi idle is double what I've got.

Interesting that your 1-2 & 3-4 shift times are so different. Have you done the vette servo install? If not you should.

Not any alt worth their salt. When my stocker goes, I'll pick one up from DC or Mechman. Will decide closer to that time as wait time will depend on what, if any service contracts they're working on

Yep, vette servo. TBH I think the 3-4 shift is an error in how the trans processes shift speed. By feel and by ear, 3-4 is the same speed as the others.

Also have a tune and shift speed reduced

Oil pump honestly wasn't bad. Worst part is having shit drip in your face. And trying to track down a pulley press tool for our engines. The one I got for Amazon just outright didn't fit despite being advertised to. And the rental from O'Reilly was a turd.

I can give you a play by play if you're interested

Good call

Interesting. Why have the shift speed reduced? I have a vette servo and no tune and the shift speed does not need a reduction imo.

Wanted a bit more than just the servo offered. I absolutely despise anything remotely resembling a vague shift. Nice and firm across the board

Popular in Canada..... ( Truck v Elk ).......

Check out the Serab oil coolers.... I had it for my (since sold) GMC C2500, for a transmission cooler, bye-passed radiator. Not cheap, but worth the money.

Always install cooler with fittings at bottom.
