Ok, so my speedo started acting funny earlier tonight. I got where I was going lifted the bed to check the connection on the rear. When I put the dump on the truck I noticed it was loose, connector retaining tabs were broken. It was loose again so I pushed it back on. Thought it would be fixed but no one of the spade things broke off. Now the speedo dosen't work and the rear abs light is on, oh well I know what broke and will fix that on monday.
The odd thing is when I was on my way before it broke I was going about 70 mph on the highway and the tach read about 1700 RPM. After it broke it was hard to tell how fast I was going, go figure huh, but I tried to drive at about 1700 again. I was getting past alot, more than usual, so I bumped it up to 2K. I seemed to be going normal speed and I figured that w/o the vss hooked up maybe the E4OD wasn't going into overdrive. I pushed the OD button and the tach went to 2500, nope that didn't help. The tranny also seemed to shift harder.

Question is does this sound normal? It sure seemed weird to me. With the speedo it was real easy to stay at 1700 RPM on the highway now I had to keep it at 2000 just to seem like I was going normal.
I just had a thought would this be because of the SD motor?

'92 F150 300-6 E4OD 4x4
Thanks,

Next question where do I get a new vss and pigtail?

 

junk yard for the pigtail- I doubt ford has one?? they may-never know till you try

 

Ya I had thought of that already and Corona's Used Auto Parts was going to be my first call tomarrow. But I'd rather have new if available.

 

Well I fixed this on Monday. I got the speed sensor from NAPA and the pig-tail from Acme. Acme has a cool chart that you can match the old connector up to. The chart and tails are from Motorcraft so maybe the dealer has them also. Ours is WPT-589. Fixed in less than 15 mins.
