Swap To 6 Speed From 5 On '96 Thunderbird? Easy As It Looks?

[mistressmotors]

I bought the complete transmission because it was cheaper than buying the individual parts. And since my bike had a problematic 1-2 gearchange, I assumed either a shift fork was either bent or worn. Luckily, all of the forks are like new!
I have a FACTORY dealer workshop/repair manual, (I worked as a mechanic in Triumph dealer, bought stuff when my dealer dropped Triumph), and yes, it IS a spacer delete/gear add on. I also am pretty sure that ALL triples and fours used identical transmission internals, save for the sleeve/6th gear delete on the Thunderbird/Legend/Adventurer. So, if a complete, good used transmission come up on Ebay- BUY IT! (I paid a whopping $45 for a complete trans from a Sprint.
The only place I have been able to source a complete engine gasket/seal set is "Sprint Mfg" in UK. Parts support for these Hinckley triples and fours in USA is pretty awful- LOTS of items NLA- No Longer Available.
I have NOT done the job yet- my bike runs like a top and as long as I'm gentle with the 1-2 gearchange, it just isn't worth taking it apart---yet. But, at some time it will.

Have a link to them for gasket kit ?

What year sprint trans ?

Sprint transmission was same year as T-Bird- 1996. I believe ALL 3 and 4 cyl bikes used same transmission internals- will spend some time checking part numbers to verify. parts for 3/4 cyl bikese getting VERY hard to source in USA.

And- have not yet done the repair/swap- bike runs fine if 1-2 shift is done gently. I guess you could say it's not "broken ENOUGH" yet!

Yes, bought a few items. Also "Pandora's" But a lot of "NLA"

So, couple years late- bike STILL shifts well enough to leave it alone! Not getting worse- though being "gentle" with 1-2 gearchange- and can still live with annoying high rpm at 80+ mph highway speeds. Too busy riding it and working on 242 Volvo 5.0l Mustang V8 swap project. Maybe this winter?
