NinaYo401 Posted March 21, 2019 Report Share Posted March 21, 2019 How does the speedometer cable attach to the ZF 4HP22 4-speed automatic transmission? I’ll get a good photo of the junction between the transmission case and the flexible speedometer cable. The sleeve/collar enters the transmission at what I’m assuming is the speedometer cable drive gear? I can’t see any method of attachment externally. I do have a transmission filter and gasket, if I need to drop the pan to change the cable. I can hear something behind the dash clicking, so I’ll make sure I don’t have the two piece cruise control cable. I’m also seeking information on pulling out the lower dash knee booster.

Mr_rye Posted March 24, 2019 Report Share Posted March 24, 2019 I'm trying to figure this out too, but on a BA7/5 transmission. I took out the speed sensor on mine (2 piece cable with cruise control) this morning while removing the clutch master. I am planning on gettin a one piece speedo cable for mine and not bothering with the cruise control. The knee panel is held on with some m6 bolts with 10mm heads, the steering column shroud needs to come off first though. its held on with some philips heads and is kinda tricky to get around the cruise control/turn signal switches Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted March 25, 2019 Author Report Share Posted March 25, 2019 I’ve read about a rubber grommet behind the brake booster. we looked at it the other day. I forgot to take a photo. Directly below the junction of the cable on the transmission, there is a bolt. Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted April 2, 2019 Author Report Share Posted April 2, 2019 Been noticing an atf looking drip in the front driver side of my parking spot. the transmission cooling lines are looking pretty soft. what are my options? Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted April 7, 2019 Author Report Share Posted April 7, 2019 I think I’m going to drain the ATF, spray the lines with brake cleaner, then a coat of harbor freight spray can rust converter. I have a filter and pan gasket. I’d like to save the gasket if I need to drop the pan to change the speedometer cable. I’ve been noticing a little highway wobble in the front right. I have mismatch tires up front, so I’ll rotate them for the rear matched pair. I’d also like to change the rear diff fluid. Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted April 8, 2019 Author Report Share Posted April 8, 2019 I was hoping to squeeze under the car without lifting it up, which I managed enough to top off the rear diff, but it was super tight with the spare tire holder. diff had a copper crush washer on the fill.

NinaYo401 Posted April 16, 2019 Author Report Share Posted April 16, 2019 Is there a drive gear aspect on the transmission end which in prone to failure? Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted April 18, 2019 Author Report Share Posted April 18, 2019 I was driving to the city yesterday, and noticed mid route that my instrument cluster brake light was on. I remember seeing a disconnected brake pads sensor when rotating my front tires. I pulled over at the closest gas station, reached up where the cable was zip tied to the brake hose. Sure enough it was loose, and possibly touching the chassis. Obviously this completed the circuit, possibly causing my indicator. allowing it to hang near the LCA, seems to have resolved the light, but isn’t at all a good long term solution. Now I need to secure the wire better, or better yet, attempt to reattach it to the brake pad. maybe I should replace the front brake pads? But the question now is if my 86 xn6 Sti calipers are bendix or ATE. Quote Link to comment Share on other sites More sharing options...
ofArc Posted April 19, 2019 Report Share Posted April 19, 2019 Here's a picture of an ATE caliper: ATEs have the cross-shaped hardware that you can see inside of the caliper above. I can't find any pictures of a Bendix caliper, but I know they have the word 'Bendix' cast into the metal of the caliper itself. My '87 STI has Bendix calipers, but I don't know when the changeover was. Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted April 26, 2019 Author Report Share Posted April 26, 2019 I still haven’t taken a look at my calipers. Thank you Arc. I picked up a pizza. Quote Link to comment Share on other sites More sharing options...
Bean Posted April 28, 2019 Report Share Posted April 28, 2019 Car looks nice in the pic! Did you get the speedo out? No need to drop the pan, but pretty sure there's a set screw holding it in. If you need new lines for either PS or transmission a good hydraulic shop can usually reuse the fittings and replace the hose part with new.

NinaYo401 Posted June 15, 2019 Author Report Share Posted June 15, 2019 I was somewhat under the car today. took a look at the speedo cable and my replacement. The speed sensor at the firewall. I should try to connect my new cable there, before messing with taking the dash apart. if I bypass the speed sensor, will anything be affected? Or just the cruise control?

Bean Posted June 16, 2019 Report Share Posted June 16, 2019 Do you have a one piece replacement? And yes - should only affect cruise. Rabin Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted June 23, 2019 Author Report Share Posted June 23, 2019 Here are some photos of the replacement cable I have. It appears different than the speed sensor end on my current cable, system I’m assuming it’s possibly a single piece. Though it isn’t extremely long, it is over 5 feet. it doesn’t appear threaded on the plastic end. that Shuttlecock may be difficult to pass through the firewall grommet, Maybe it’s removable?

NinaYo401 Posted June 25, 2019 Author Report Share Posted June 25, 2019 If my current speedo end looks like the new one pictured, I could possibly use bailing wire between the transmission end of the new cable to it and pull through the firewall with the old one. Im wondering if I should remove the knee bolster to give myself some working room. While in there, maybe I could disconnect the central locking relay. And maybe ditch the cruise control lever.

NinaYo401 Posted August 26, 2019 Author Report Share Posted August 26, 2019 Finally figured out how the cable passes through the firewall, found the cruise control speed sensor, where the two halves of the speedometer cable join. i also pulled out my gauge cluster, and noticed the cable is disconnected, but also seems to not have enough slack to connect, unless it stays in that position, and the cluster is pressed onto it ss a mooring. I guess I’ll attach cable, then fish it through the firewall. the silver end pictured above, connects to the transmission. It’s the connection I’m wondering about. Does anyone have information on the set screw to detach the transmission speedometer cable drive end? I’m hesitant to loosen anything on a transmission Quote Link to comment Share on other sites More sharing options...
Bean Posted August 26, 2019 Report Share Posted August 26, 2019 There should be a set screw or similar holding the end in. Cable has always broken at the tranny end for me, and yes the cable gets seated once the cluster is in place. Rabin Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted August 26, 2019 Author Report Share Posted August 26, 2019 The end of the cable looks very similar to the method which the brake hoses clip to the chassis. I’m afraid it’s a clip internally, which would require dropping the pan. Though I do have a new filter and gasket will I loose ATF from the speedo cable drive?

NinaYo401 Posted September 6, 2019 Author Report Share Posted September 6, 2019 I ran the new cable from the speedometer into the engine compartment. I tested it with my drill, and the gauge seems to work. I’d really like to change the transmission filter, but the dipstick into the pan is daunting. Can the dipstick be detached from the body and left attached to the pan while dropped? Or is the dipstick simply detached from the sump pan? I haven’t identified the set screw for the speedometer cable yet. It’s a bolt? Quote Link to comment Share on other sites More sharing options...
NinaYo401 Posted September 10, 2019 Author Report Share Posted September 10, 2019 The new cable was easily attached to the transmission using the closest nut to the speedometer drive cable, very simple. I completed the task using ramps. however, I now have a noisy and bouncy speedometer gauge no ATF leaked or was lost from the drive. I used Synthetic multipurpose grease, and cleaned the transmission end with Wd40. Maybe I should use some combination on the speedometer end Quote Link to comment Share on other sites More sharing options...
