I am changing transmission in an 86 blazer 6.2 liter (Jcode) diesel from a 400 to a 700R. Does anyone have a source or part number for the detent cable, and detent cable bracket for the injection pump? Having a difficult time finding parts locally. Thanks Cory
I don't have one (not in use), but the cable that goes to the pump is the TV cable (Throttle Valve). The "detent" cable is the "range selector" cable, and connects the shift selector (on the steering column) to the detent lever on the side of the tranny.
The TV Cable is best bought new as they can stretch or become damaged over time.
There is a bracket which bolts to the back coolant block off plate on the drivers side head which the TV Cable snaps into and then a metal rod which attaches to the injection pump throttle lever.
I am trying to sell the 700 which is in my truck currently and going 5 speed. If you dont have any luck on the brackets I may be able to help you out in a couple of weeks.... (Dont know how long you want to wait).
Do yourself a huge favor and find a friend or source a Pressure gauge for measuring transmission line pressure. The only real difference then a normal pressure gauge is that it comes with about 4-5 foot of hose so you can monitor the pressure in the vehicle. 700's are very finicky about improper TV cable adjustment as it controls the fluid pressure through the transmission. If you dont check the pressure your gambling that the Line "Set" in the proper position when you first install and adjust it and if it is out of spec then you will find yourself replacing the transmission very soon.
Thanks guys. Would be very much interested when you make the change. Contact me by email. corymkishp2@gmail.com
Hi Guys New here but have been doing some reading here.
I have a 84 gmc 6.2 that had a started issue grinding. So I replaced the flywheel and finally got it back together after about 3 months. I got it started and took it for a drive but Im getting a shuttering affect ( its shaking and shimmering ) Does this relate to the TV Cable in any way ???
I didnt undo the cable that I know of. I worked mainly on the bottom end of the truck . Seperated the tranny from the block and installed new flywheel. If its out of sink or tune ( TV cable ) will it do this. I only drove it around the block. Now Im kinda feeling depressed about this driving crappy. Any help
If someone has one, send it to me and I'll shoot the photos and produce a drawing - then return it to you. Would be nice to have a drawing on file...Quote:

This bracket must be exact in order to allow the TV pressure to be exactly adjusted.
I have one, maybe two of these.
Let me know

I have a couple of brackets that I picked up last summer. They are for some projects.Quote:

Thanks,

Going out in the mail today.
It will be crossing paths with the 6.2L books I just ordered.
Just send it back when you are done.
Thanks,
Joe
MorePower, Any chance of getting a file of the drawing if and when you get to it??
