M1028A1 TV Cable Bracket Installation

Howdy folks, I am in the process of a TH400 to a 700r4 swap in my M1028A1. The new transmission is in and just about everything is done except the cooling lines and lockup wiring. The truck did not come with a TV cable bracket, however, I was able to source and procure one.

After connecting the TV cable I am no longer confident I installed the bracket in the correct location. The cable does not seem to want to return at all until throttle returns to resting position (truck has no yet been started since doing this swap). I removed a water sensor from the rear driver side of the engine and installed the bracket on top of the water sensor mount using the same bolts which held in the water sensor. I realize I may need to take some pictures, however, that might not be easy.

The part # of the cable I installed is 25515599

First off....



Welcome to Diesel Place !! The Big Show !!


The TV cable bracket can only go on the rear set of bolts/studs so I doubt you got that wrong. From my semi foggy memory, I would say the cable is acting correctly as there is some slack in it, if it was set properly in the first place.


To set, press down the adjuster tab and pull the TV cable towards the firewall, now release the adjuster tab and the cable should stay in that spot, now hop in the cab and press the throttle down all the way twice ... your done.


Driving will tell you if it's set right on not. If it up shifts too soon and softly then there isn't enough pressure in the cable and you can take out a 700 pretty quick without enough throttle pressure.

Howdy Bigboytoys, thanks for the warm welcome! I just uploaded a video to youtube showing the motion of the linkage and the location of the bracket. After messing with it some the motion of the cable seems to be a bit smoother now. I thought maybe the cable was hanging up because of its extreme angle going into the socket on the bracket.

Here is the video link:

Looking for some opinions as to the cable's motion, tension, and the bracket's location.

Thanks!

Looks like maybe that tight bend by firewall might be causing it to bind.
If you unhook it from the IP does it move freely or can you feel it still binding. I would then unhook from the bracket and see if it still binds.


The throttle cable on my K20 was binding so I made the loop go a different way and the binding was gone.

Ya it's a fairly tight spot & design GM did.


It almost looks like you have a twist in the cable cause all of mine have sat straight up and down.


One nice side of the cable hanging up is adds throttle pressure which is the opposite of the trany killing too little.

I was able to play around with it and get the cable set in a position where it now follows the throttle like it should. However, when I press on the throttle pedal in the cab it feels a bit stiffer than before. Is this normal?

I put at least 500 miles now on the 700r4. It seems to be working great thus far. The hottest it ever got was just over 200 degrees. Lately it has been running less than 190, but, it is getting cooler outside. I am in the process of mocking up and installing a commercial truck transmission oil cooler. I will need that before I can start towing.

Ya I would install a trany cooler cause 200 pretty hot for a 700.


Are you sure the TC lockup is working,?? You'll feel it get really responsive and solid feeling to throttle input when the TC locks. It can be either in 3rd or 4th depending on the year and valve body.

I installed one of these during the swap: https://www.summitracing.com/parts/b...SABEgJSffD_BwE

I can definitely tell when the converter locks up. The way I have it setup it'll shift up into OD, the RPMs audibly drop, then the converter locks up shortly after and the RPMs audibly drop even more and I get a more positive response from the pedal.

Ok, pop in a quite large cooler and you should be good. My 700 runs about 140-150ish
