Looking at a very clean low mile 06 truck 5.3 that i would like to use in my 72 k5 blazer. I want to use a 700r4 transmission and np205 transfer case. My biggest concern is if it would be possible to use the tv(kick down) cable from the transmission...how would it get input from the throttle body. My first thought was that it wouldnt be possible so i though i would ask here if anyone was doing it.
thanks
Mark

 

or has anyone used a np205 behind a 4l80e with success?

 

I'm using a 700r behind an ls1. I'm going to use a tv ls1 kit from bowtie overdrives. Hope this helps. John

 

thanks looked at there kit and it will work if i can convert the throttle body.

 

I don`t know if anyone has used a np205 behind the 4l80e.

For the TV cable you could make a bracket/system to connect it to the gas pedal instead of the TB. Someone else on here did that and there is a thread about it. You have to be very careful if you do that, the TV cable needs the correct amount of travel and in the correct arc.

 

im thinking either an older motor all together or try to swap the tb to a cable throttle type....but that would change the harness' needs.....waiting to hear back from speartech on what it would take....might not be worth the effort.

 

i, too, am curious if anyone's put an np205 behind the 4l60e.

 

i dont see the benefit of a 4l60e....i would rather have a well built 700.

 

you're probably right, i've just got my eyes set on a 5.3/4l60e package out of an '07 tahoe...

 

a 4L60e won't need a TV cable... and won't need any fooling with springs. It's all computer programable and likely has a few better parts than the older 700R4.

 

i know this was a long time ago but did you ever figure out how to make it work,im in the same boat

 

onetonk5 was last here in 2015.

 

I run a 4L80E and NP205 in a tow truck, worked for years. Used 2 wheel drive transmission with output speed sensor in transmission, TH400 adapter, a spacer and trimmed output shaft shorter.
