Default 1996 LT4 reverse lockout

Is the '96 LT4 supposed to have a reverse lockout?

If so isn't suppose to prevent, even under hard acceleration and spirited driving, the driver trying to quickly shift from 5th to 6th and accidentally shifting into reverse gear and grinding gears?


Thanks,

Trebor

Why do I get the feeling this has a story to it?

I'm pretty sure that by 1996 rolled around every car in America was required to have the reverse safety function......What did you do?

*edit*
Short version

Standard No. 102 - Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect - Passenger Cars, Multipurpose Passenger Vehicles, Trucks, and Buses
(Effective 1-1-68)
This standard specifies the requirements for the transmission shift lever sequence, a starter interlock, and for a braking effect of automatic transmissions, to reduce the likelihood of shifting errors, starter engagement with vehicle in drive position, and to provide supplemental braking at speeds below 40 km/h (25 mph).

I did a little research (someone correct me if I am wrong) ...the earlier ZF transmissions had a lever that you manually lifted up in order to go into reverse...otherwise it could not go into reverse while moving forward.

The "new and improved" later models like '96 were treated to a "passive lockout" system which included a heavy spring that resisted shifting into reverse while moving forward. Not sure what year this was introduced.

The passive lockout seems way less protective since under adrenaline driven type shifts, it can easily be overridden, right?

Can someone better explain the mechanics of this passive lockout?

Thanks,

Bob

96 is crash through - no pulling up on a ring below the **** to shift into reverse. I don't think its dangerous by any means. Consider that under any type of spirited driving you're not going to be going for 6th anyway, and hence won't accidentally try to put it in reverse.

The only reason I like the lift ring on my 94 is in the event that someone else drives the car they can't mistake reverse for 6th.

To go into R, requires effort and thought. Maybe someone drunk, on drugs, or who flat out can't drive a manual transmission *might* be able to accomplish that while driving. I've never heard or read of someone screwing up in this manner.

It hasn't been a problem for me. As was mentioned, You are rarely in a hurry to shift into sixth.
