My Mangusta speedometer needle bounces a lot when I drive and I can hear whirling noises behind the dash. Is there a replacement cable or do I have to disassemble the cable and lubricate it?

You probably have a kink in the system somewhere.
Check the transmission end and be sure that the cable housing is tight and that the cable ends are well tightened. Also see if there are any sharp bends in the cable after it starts forward from the transmission. the cable housing should travel toward the front of the car in smooth easy curves.
After that if nothing is found take the cable out, clean it well and use some dry graphite lubrication, no oil or grease as that can go into the speedometer and mess it up. The gears could be worn although they should not be.
>>>>>>IMPORTANT
Do not take the little drive mechanism on the transmission that the cable screws on to off as a piece of it can drop into the transmission when you do that if you are unaware that it is there.
Once that happens you have big problems. If you decide that you have to check the gears get in touch with Guy Trigeaux first at >gt4-2860@charter.net< a ZF expert. He can help you.

Thanks for the advise Dick. I'll do that. By the way Wilkinson Pantera has a NOS Mangusta speedometer cable in stock. Ben
Well I ordered the Mangusta speedometer cable form Wilkinson Pantera and tried to install it. The original cable routes through one of the square tunnels under the car. The cable from Wilkinson was the correct type but about a foot and a half too short. I had to route it under the car where the stock parking brake cable goes and zip tie it so it does not hang and make a shorter route around the steering rack direct into the speedometer. It works for now and the needle does not bounce at all. I have sent the original part to Wilkinson to reproduce to the correct length.
