Transgo shift kit

[jack1911]

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

there are other tricks for the accumulator , you might want to watch Precisiontransmissions videos on upgrading your trans parts.  check out his youtube, and search for your transmodel in his channel
