I think just first. if you want to shift to first while moving above 10 mph, you have to REALLY want it.

 

strange mine does it for all the gears once when i was driving on the highway trying to get to dallas quickly i was going probably about 90 and tried to go almost missshifted into 2nd it wouldnt let me it bounced of the gate. i know it does it for 1st about 10 i think 2nd its anything above 70 it wont let you in.

 

^^^ I have never tried to shift to second going 70+.
The most I will hit second from is about 40.

I dont feel comfortable dropping in higher than that.

 

As long as my car is at 60 or below, it gets dropped into second if I need to go.

Could that secret bullitin I posted earlier with the non tempered timing set of broken a roller on the timing causing one of your cams to quit turning and cause this damage?

edit: just realized I said that all in one sentence LOL
