(got my fingers crossed for cable). Thanks...

Just thought you might want to know about that. | | | | | Joined: Jan 2003 Posts: 354 'Bolter | | 'Bolter Joined: Jan 2003 Posts: 354 | It looks like the one on the T-5 I pulled. It's a cable drive adapter. If you look closely you'll probably find a number on it which matches the OD ratio of the transmission. My guess it's used to adapt an OD transmission into a vehicle with a speedometer calibrated for a non-OD transmission. I removed the one on mine since I still have the original rear gear. Following my wife in a Yukon my speedo reading appears to be correct.

So based on what you're saying, this is a mechanical drive speedometer cable with a plug-in adaptor?
Chris | | | | | Joined: Jan 2003 Posts: 354 'Bolter | | 'Bolter Joined: Jan 2003 Posts: 354 | Yes. The adapter has a threaded nut just like the one on the end of the speedo cable. That's how it's attached to the transmission.

Clean the top off,there should be a sticker decal with the model number.They start out with 1352-???.See this link for Identification.
