Dial indicator

How do I repair the indicator on my steering column that indicates what gear I am in? Is it neccessary to take off my instrument panel? Do I have to unbolt the steering column? I am aware that the indicators fuctions on a cable that resembles a fishing line. My manual absolutly does not show a thing how to hook the doggone thing backup. I think it just popped off and is not broken. How do I reconnect. My vehicle is a 1987 5.7 chevy suburban. Auto trans of course. Let me slip this question in to. How do I adjust the indent cable? The cable is beginning to unwind where it is connected to my TBI. Some times when I am going up a steep hill the accelerator does not kick in to I guess what you would call passing gear or overdrive. Please give the the run down on this cable. The tranny is in good shape, I suspect the cable. Thanks

Tommy

to repair the cable no you just need to pull the lower panel under the column around it


to remove the indicator plate you have to remove the instrument bezel to get to the two screws that hold it to the dash cluster housing

anymore details needed lemme know


or pics i can take pics i have several 73-87 dashes laying around and plates also.

to reconnect it if the cable is not broken you simple pull the loer coverpanel under the column around it there and it either clips to the loer column housing at the dash,. or it is retained by a phillips head screw

both styles were used over the years and it will randomly have either style


most times the cable is frayed broken though

as for lack of kickdown if it is theoverdrive trans(700r4) then it is actually not a kickdown cable but rather a TV cable

if it is the 700r4 then you have to fix this asap as this runs the transmission and if it is badly out of adjutment or fraying then it can cause the trans to burn up the forward shift clutch pack due to sloppy slow shifts or cause undue strees due to too harsh of shifts.

it may have a 400 trans however

if it has no overdrive position

3L80HD in that case, a variant of the th400 starting in 87 and has a 27 spline output most were tag code LJA on the side of the trans i have two of them both from 87's

and they dont have a cable

so since you say you have a cable then it cant be the 3L80HD trans and must be the 700r4

buy a new cable for it at auto zone or napa etc and set it properly, ASAP




good luck

TV cable

Now you got me worried. I definitly have a TH700R4 trans. What are the signs that I hav'nt already burned up the shift plates? I just recently changed the fluid and it did not have a burned smell to it but never the less tell me more about this TV cable. What does TV stand for? I will get it repaired but I need information on how to adjust it.

TV cable = TV/ThrottleValve Cable >>>> "The TV cable used on the 4L60 (transmission AKA THM-700-R4), THM-200-4R & THM-200C controls line pressure, shift points, shift feel, part throttle downshifts and the detent downshifts."

It's a good Info link, no doubt. I think Crosley/Tony is to thank for most all the 700R4 Info, maybe much more. I haven't looked thru all of the other links yet. Check out the 2 links at the top of the page. There's all kinds of Great Info. & odd things. I like the Fool Injected 427. http://purplesagetradingpost.com/sum...carsindex.html and Crosley's Isetta/Erklemobile.
