Speedometer cable
Does the speedometer cable screw into the transfer case on the drivers side just before the rear drive shaft?
The transfer case is a NP205 from a '72 K10. I have a transmission fluid lead and it appears to be dripping from that cable which has what looks like permatex gooped around it just after the fitting to the trans case. Does the transfer case have transmission fluid in it? |

Re: Speedometer cable
Mine leaked there til I installed the cable. I needed a longer one due to modifications.

Re: Speedometer cable
It isn't supposed to have transmission fluid in it. What is happening is the seals on the drive sleeve in the tans/transfer case adapter are allowing transmission fluid into the transfer case. Or theres a possibility that someone did fill it with transmission fluid and if thats the case you should change it to gear oil.

Re: Speedometer cable
Just to confirm what's already been said.... yes, that's the speedo cable and no, the t-case shouldn't have ATF in it. It should be 75W90 or 80W90 (or even straight 90 weight, but nobody seems to use that anymore). The good news is, ATF has excellent lubricating qualities so it's doubtful any damage has been done. In fact some t-cases call for ATF. Years ago, I had the bad seal mentioned above and had to occasionally drain the excess fluid from the t-case, and fill the transmission.
