Default 2.73 gear question

Does the factory have something that locks out 1st gear on an atuomatic car with 2.73s if so why and is there a way to get it token off?

they put a rubber bump stop where first gear select would be. they did that because it would downshift and not meet the noise requirements. all you have to do it cut it out.

Cause you got the 3.23's, mine does the same thing(factory 3.23, GU5 Code). There is a little rubber stop on the linkage in there that stops it from going down into 1 on the 2.73 cars. Like said earlier, you take it out, and it will go into first.

From what I have heard, if you have 3.23's you can shift into first. 2.73's you have to cut out the little rubber stop off the shifter assembly. I cut mine off` and now I can go into 1st. I have 2.73's

Wow.. I did not know that. I am definitely doing this! Hell I don't care if it's 10* out. Is there perhaps a writeup or picture someone has?

my brother and I both have 94/95 Fbodys and we figured out it will go into first, you just gotta slam the shifter down. After you do it a couple times it will be easier.

all you have to do is remove the center console cover. try to put the car in first and you will realize whats blocking it. cut that out and you have a whole new gear.
did it last week.

I wouldn't see how forcing it into 1st will work. I cut the rubber out today and can now go into 1st gear. Pretty awesome since most roll races are from 1st gear. But anyways, the rubber is thick/solid as hell and supported by a metal tab. What I realized is there is actually two rubber stoppers. What I think happened to those who say they have to slam it into 1st with 2.73s, is someone took out one off the stoppers only (the small thick one).

Here is a picture of the other large stopper that is farthest up front. It's more spongy
The impression you see is from a rod that begins to touch it in 2nd gear. Then it pretty much stops it from going to 1st.

Here is a picture of the small rubber one that is really thick.

Place it back in where it was and then take a pic, so some of these guys know where it is and can take it out.

You couldn't pay me to do that again. Had a hell of a time with it and pissed I cut my leather on the e-brake handle. But I'll show you this... The red circle is circling the rod I talked about.. the stopper is RIGHT under it. The green circle is where the thick rubber stopper is located.
