I was thinking about getting a transgo shift kit for my 2013 Silverado 4.8 4x4 4l60e. But I can’t seem to find much on the nnbs. Do anyone know if it will work. Also is it a bad idea to just install a corvette servo by it self?

I use to use shift kits. I quit when electronic tuning became available. Hand helds gave the same feel by removing TM.

You can install the corvette servo.  Not sure the difference on your transmission than when I had my 2002 Silverado.

Removing TM and adding in a shift kit is much different imo they may give the same feel but with a shift kit you aren't gonna break ****** quicker

 

No it is not a bad idea to install the corvette servo by itself.

Here is some info on the NNBS. I don't really know a lot about it either. You may want to call one of the trans builders and ask them. Jake's Performance perhaps

I have already installed the vette servo. My 1-2 shift before was sluggish normal driving if I got onto it, it wouldn’t really change. So I added in the vette servo and normal driving it shift quick but if I get onto now the shift hard IMO. I’m assuming if I replace the 1/2 accum. With a pinless accum it would resolve this issue or should I just have it retuned.   This is my daily driver. I want to be able to romp on it and not worry that I’m going to kill the trans. I have a cai free flow exhaust on 33s.

Yeah the servo changes the pressure or somethin like that. That sounds normal operation to me.

 

You will be fine if you leave torque management on. It's a 4.8 lol I would not worry too much about it

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
