So here is the history...... when I bought my Saleen 11 years ago, one of the many things I replaced was the speedo cable because the one that was in it was melted by the exhaust. Even though it was working, I changed it with a used one from a Pinto. The Pinto one was an inch or two shorter than the one that came out of the car but it still fit and tucked up a little better around the exhaust. Up until a few months ago, I had no problems with the speedo. It started acting up when I would get off the freeway, on my way to work. It works just fine till I get to that light and stop. When I take off again and get up to 45-60 MPH the speedo starts clicking and the speed does not get above 25-30 MPH. I still have another 4-5 miles to go before I get to work. I get to work, park the car and let it sit till I go home. On the commute home, there are no issues. Thursday I took the Saleen to work, first time in about 3 weeks, and right off the bat the speedo was acting up. It works, then clicks and doesn't work, then it works again. It did that on the way home as well so that evening I took the speedo cable out to clean it. I pulled the cable, out from the housing, cleaned it. I cleaned the inside of the housing with brake clean. I lubed it with ATF but it would not slide in all the way. There was a spot that would hang. I had a couple more spare Pinto speedo cables so I got another one and cleaned it all and lubed it and that cable slid right in to the housing. I put my speedo gear on the end of it and back in the car it went. I went for a 5 mile test drive and no issues. This morning I take it to work and all the way to the freeway, the speedo is acting up. Then when I get on the freeway it was fine the rest of the way in.
Even thought the cable is used, I am pretty sure it is fine. It is cleaned and very well lubed. The speedo gear is fine as well. I put a new one in it when I put the 3.55's in it a few years back. Teeth looked good when I had it out with no wear that I noticed.
Any ideas what to look for next? It only leaves the speedo itself or the transmission drive gear, in my opinion. If it is the drive gear, would the speedo be clicking like it does up at the dash? Any help would be appreciated.
