Pre 78 transmission and overdrive gear

[bloglos]

Hoping to get some clarification. I understand that the Mike's XS 5th Gear overdrive is meant for the 78 and later transmissions but I was told it "should" work fine in my 77D as long as it's also installed with Mike's 05-0857 (Gear - 5th. Main - 22 Tooth)?

Can anyone clarify this for me as I'm about to split the cases.

I read that, and I'm probably an idiot but the way it's explained is confusing me. I just want to know if I can slap the overdrive gear (05-0870) and Mikes 5th main gear (05-0857) in my older transmission (77D) or is my only option to order a 78 transmission and then add the overdrive gear.

I swear I'm not trying to drive you crazy weekendrider, I appreciate the help, but is that a yes to I can slap the 2 gears in my old transmission, or a yes to my only option is to order 78+ transmission?

Doesn't skull's post say that you don't need to swap both gears?

Depends on what engine no is in your 77D.

Why post another thread on this when one is already running

Read the service bulletin i posted in the other thread. It explains the differences, why they shouldn't be mismatched and when the changes were made very well.
