06 Tundra driveshaft & steering rack ??

If you have a 4-pin, you don't have TO.

If you have an OEM 7-pin and factory receiver, you likely have TO.

 

Fair enough.
But what about the trans coolers:
IE: Is there only one Trans Cooler spec'd for the 2WD v8 drive-train whether TO package or not?
Or, is there a HD Trans Cooler for the 'TO package' but others just recieve a standard duty unit?

Almost sure this will be booted to a new thread.

 

Not sure. Check the megathread, there’s links to feature/catalogs near the top @BubbaW was kind enough to pull together, and you may find that info in there.

 

I have the same sticker on my drive shaft and I doubt it's ever been replaced.

 

what's the best alternative since the Dana Spicer part has been discontinued?

I've got to have a new driveshaft, carrier bearing, and U-joints.
