    Custom Tune Review!

    @NickTransmissions thanks for your quick response and information! Where are you located by the way? So to respond in order: -No check engine lights or codes according to a scan with the GM Tech2. 1. Adapts (or lack thereof) resulting from either mechanical issues, programming changes -- a...

    Custom Tune Review!

    @NickTransmissions Hey Nick! I have been seeing you getting really active here and I am relatively new as well and trying to contribute but my current job and 5 kids keep me busy. I was hoping to maybe get your opinion on my situation which I will summarize below so you do not have to read...

    2011 Tahoe Pad & Rotor recommendation

    I’m going to have to do the fronts on my 2011 with 97k as well. Pads are 4mm but I’m getting some pulsating now. I have always had good luck with Centric rotors and posi quiet pads and thinking of trying that but the size of this truck makes me think I need something a little stronger...

    2012 Yukon Denali strange noise after truck turned off

    Try engaging the emergency brake and see if it changes anything. Almost sounds like a creaking e-brake.

    Custom Tune Review!

    There seems to be conflicting opinions of the valve body. I am trying to decide if I should try and re-build it myself or just buy the remanufactured one from Sonnax at Rockauto but I definitely want to move forward soon. I am leaning towards just doing the Sonnax valve body, rebuild the TECHM...

    INPUT ON TRANS PAN DROP, FILTER, GASKET & FLUID CHANGE

    Did you do the slight bending of the exhaust to get the pan off and out? I’m mustering up the strength to try and do the valve body and rebuild the TECHM.

    Custom Tune Review!

    So in my research of the transmission and valve body I found the Sonnax article found below regarding an added 8th checkball into the valve bodies starting 2014 due to customer complaints of a rough shift from 2nd to 1st. Wondering if this would also help my 3-2 gear? I was going to contact...

    Custom Tune Review!

    Unfortunately I don’t know the history of the car but the fluid was red before I changed it! I have been driving the truck a little bit more and all upshifts are ok except I get a little flare from I think 3-4 and then the rough down shifts. I’m definitely leaning towards trying the Sonnax...

    Custom Tune Review!

    Funny timing as I just re-read through your journey the night before last! That is part of why I thought about doing the already rebuilt valve body and then just doing the TECHM re-build. I will definitely reach out to you for additional questions as I am still assembling what I think I would...

    is anyone with a tech2 local to Philly area ?

    Hey so I am running into some trouble with my tranny as well that not many people seem to have a problem with. Everyone says 2-3 shift but mine is actually 3-2 when stopping. Looking at doing the same thing you did and wanted to see how yours went. Did you find a tech2 local to Philly?

    Custom Tune Review!

    O What all can the Tech2 tell me about the trans that the HPTuners didn't show? The Tech2 can do the trans adapt if I change the valvebody correct? I called two other local transmission places and they do not rebuild the 6l80s either. That is now 4 places I have called and they all only do...

    Custom Tune Review!

    Yes I am referring to a harsh down shift from 3-2 mostly. Sometimes it’s harsh from 2-1 sometimes it’s not. However, it’s never harsh on up shifts at all. Only when it’s hot downshifts when coming to a stop. Would the remanufactured valve body by Sonnax on rock auto be a good option? If I did...

    Seat Swap Captains for Bench

    Check out some local junk yards because I found a small salvage place in northeast Philly on Facebook market place that I just bought a second row bench to replace my captains with for $200!! They actually had three sets, two perforated and one not. Overall good condition too! Not sure if...

    Valve tick or normal sound?

    So I installed an oil catch can this weekend based on info both here on the site and others and upon completing it and take it for a ride, I feel like the valve tick is getting louder but wanted to see if others agree. If anyone has time to compare this video to the first one, it sounds like...

    Oil pan gasket leak?

    I was thinking of trying that just to see if it would help. I had a very similar leak and started a thread a few weeks ago and just haven't had time to get pictures posted. My leak to be in the same location, the back corner of the oil pan gasket or the rear main, which it appears dry in...
