Re: How much damage .
Seems like it should be ok to me. You should be able to do 65 mph in second gear, plus the potential damage would be from over-reving the engine (rather than your trans - which doesn't seem likely).
Give it a few days and see if it is just your imagination. K

Re: How much damage .
Thank you sir for the reponse the shop guys told me the same thing but it feels weaker and sounds a little funny but might be my imagination about worring and over thinking it. The truck just hit 40000 miles on both eng and trans

Re: How much damage .
I agree with Keith, that engine damage would be more likely than messing up the tranny. Its probably your imagination cause that seems to be a big culprit with most noises and feelings with the vehicle.

Re: How much damage .
I knocked may last Turbo 350 into reverse at about 45 and it lived. You are imagining things. Jay

Re: How much damage .
I've hit mine into park a couple of times while moving (after the engine had died and I needed to re-start) and it's still here.

Re: How much damage .
Yeah im with Keith over reving your engine would cause more damage faster then knocking the trans down a gear.A turbo 350 is a pretty strong trans even stock i wouldn't worry about it just don't do it again lol.

Re: How much damage .
You know hitting reverse at 65 is something to worry about, but I have done it in the past. That is why I now have floor shifters with a positive lock for going into reverse. Dropping into second at 65 is not that bad, and it may have shaken you up more than the truck.

Re: How much damage .
this must be a common problem with these squares, i knocked mine into neutral on the highway while messing with the radio too.
