so last night i was coming home from camping. i was driving on a dirt/gravel road for about 30 miles or so and right toward the end i noticed that my speedometer was showing wierd readings. like bouncing between 30 and 50 mph. so i went to try to see if the cable was loose on the back for the gauges, but thats a bitch. gave up. then iw as driving and i head something bouncing around and stopped to see that my speedo cable came out of the transmission. has anyone else ever had this happen? and also i havent stuck it in the air yet to fix it but does anyone ahve a pic of where it plugs into the tranny?

 

you will see where it goes as soon as you jack it up. Its on the driver side tailshaft area

 

It's the best I can come up with right now.

 

thanks tkp3200. that should be enough info for me to figure it out

 

If the speedometer cable came out, then so did a good portion of your transmission oil. Check the level and top it off before driving the car. There will be two 4-sided plugs threaded into the side of the case. Unscrew the top one, and if oil doesn't start to run out, it's probably on the low side. You can stick a finger in to see if the level is just below the opening. If it's low, you might as well drain it all and refill with ~2.5 quarts of 75W-90.

 

so today i stuck it up on the lift and put the cable back onto the tranny. checked my fluid in the tranny still pretty full. found out i needed new tires. but once i got it off the lift i was driving home and it still didnt work. wtf :S

 

its 1 of 3 things...

the cluster
the cable
the drive gear in the tranny

probably not the cluster unless it came unattached...

 

well imma go with the cable. it drug on the ground for a while before i furgured it out. and the end was pretty banged up. anyone ever replace a speedo cable? how hard is it?

 

and also my dad mentioned something about most cable driven speedos use like a common cable, making it fairly interchangable in the case of something like this happening. is this the case for my 7? or do i have to find the special one just for my car

 

get an fc cable, they are cheap. it takes about 15 minutes to replace.

 

i was lookin on black dragon and it was far from cheap. something like 100 bucks.

 

Same thing happened to me, ive put it back, and i couldnt get a reading, so i take it off again, and i noticed that the cable inside is broken, you just have to buy a new one, and install it, should take an hour MAXIMUM, only like 5 screws on the cluster and thats it!

mazdatrix has them for $65

 

LAME!! imma check the junk yard tomorrow. he has an fc sittin there. imma try to talk him outta the whole car
