Speedo DEAD wont shift?

[SIXSIXSIX]

Got in my 98 camaro and was going for a ride.Noticed that the speedo was below the 0 mark.the speedo does nor work now. also the car would not shift.Does the speedo affect the trans?
Anyone seen this before.Can I get a part to fix this.?
Thanks

my gauge cluster went bad once, something with the contact points and the wiring.

Also, when my alternator died on me, the whole cluster just went wacko. (I think that's the technical term.)

Check your tranny fluid.

Another shot in the dark : I'm not sure, but the computer may be screwing up and thinking you're at the limiter . . . check your wiring.

hmm wiring.hope its not wiring.
anyone else know if the speedo is related to the tranny shifting.this car does have a jet scu 2000.im not very familure with this item.it was on the car when i got it.to corrrect the speedo with 342s and 18 inch tires.hope someone on here has had this problem before and can point me in the right direction.:0

it's the scu2000. either it's not set right or it's dead. that means no signal is reaching the computer ,the speedo isn't getting a reading, and the car will not shift because the computer doesn't know how fast you are going. take it off, check your setting, then go through the whole installation process of disconnecting the battery and all that. if that doesn't work, it's time for a new module.

hmm ok.so if i take it off all together then at least the car should shift then right?I have the directions in the box but i have never folled with it.does it hook to the ecm or into the trans.appreciate the help!thanks

going to try to disconnect the scu 2000.and make sure it has power.anyone have anymore ideas?

Its definately the scu I had the exact same problem.

Unplug it and plug the normal wire back in and you should have a speedo again! I ended up having to get a new scu2000!

Same problem here too. Disconnected my SCU2000 and left it off.

I'm guessing you guys don't have good power connections for the SCU..

it's VERY finicky and needs GOOD SOLID power.

It was the scu 2000.I left it off.now my speedo is off about 13mph with 342 GEARS AND 18 INCH CORVETTE WHEELS.WISH I COULD MAKE THE SPEEDO A LITTLE CLOSER TO RIGHT.LOL
