t56 no gate for reverse?

2004 GTO converted to a Manual

**Chinesium shifter looks good, but geometry is off. Mechanically does not go far enough to engage reverse.**
**Fix was installing stock shifter with Lou's short stick.**

My GTO is at the shop getting completed / tuned. I got a call that the t56 won't go into reverse. *Correction, the shifter won't even go into the gate.* Its acting like the reverse shifter gate doesn't exist. Has anyone heard of this happening and/or know of the cause so I can assist them in quickly solving the problem?

The 3 things I thought of:
• I didn't install the fuse for the reverse solenoid. *Supposedly not the issue.*
• I accidentally flip flopped the connectors for the reverse lockout and cags. *Supposedly I didn't.*
• I installed my chinesium shifter (that looks like a gmm rip shifter) too high. I left the stock gasket on when I installed it even though it comes with a rubber ring gasket that fits into a machined grove on it. *No confirmation on that, but I doubt the half a mm height difference would cause this issue.*


I bought the transmission used from Hawk's Motorsports and it supposedly only had 65k miles on it, came off a 2006 Orange GTO, and worked fine. Not that I am questioning their integrity; the people at Hawk's Motorsports are awesome to deal with and very polite.

Any thoughts?

First thing i thought of is the connectors getting swapped.

Try removing the solenoid and seeing if it is stuck.

Looking at those shifters, the handle looks like it can bolt to either side of the "stub". Which side did you install handle on?

If on the right, could the handle or the bolts be in the way, so to speak?

I did install the shifter arm on the left because I thought about it being an issue if it was installed on the right. But good thought.

I had a similar problem a few years ago. Nothing, I mean nothing could get the car into reverse. Finally, this was during the summer, I let the car cool off and was able to get into reverse with the motor off. It would not go in while running.

Turned out to be the Cags, and even though I had the Cags delete, the mechanism in the tranny hung up and locked the car out of reverse. The cure came when I disconnected the Cags delete, disconnected the battery, and after a time reconnected the Cags delete and the problem disappeared.

But, a year or two later reverse locked out again, and it happens now and then to this day. Don't ask me why. But when the time comes to rebuild the tranny, I will take out the mechanism. You have a new install from a former A4 car. I would start looking there.

Appreciate the info!

At this point its out of my hands, hoping to hear good news soon.

Only 20 more days, then it'll be a full year since I drove my GTO.

Thinking about it, I've driven my GTO a total of a week in the past 3 years.

What do you mean out of your hands? What did you do?

I already texted them what to check and they know more than me, so it's currently out of my hands.

Update

It is not the reverse lockout solenoid. CSP believes the transmission I bought from Hawks Motorsports is internally damaged. It will not go into the reverse gate at all. It physically will not go further over to the right beyond 5th and 6th. I spoke to Ryan who suggested I try a stock shifter incase there is something wrong with my aftermarket shifter. I doubt this is the issue but he said to give him a call after trying so why not.

If this transmission turns out to be dead, this would be the 7th that's been in my car...

Would of been cheaper to simply buy another GTO.



Since I swapped shifters before ever testing the transmission out, Hawks Motorsport thinks my aftermarket shifter is the culprit. I cannot dispute this since I never tested with the stock shifter. The reason I swapped shifters in the first place was because the stock shifter I received was smurfed up.



Here is what I replaced it with:






So.

I'm taking off work Friday to drive a hour to NJ from PA to pick up the stock shifter, drive another hour to CSP in PA so I can swap shifters to see if it will shift into reverse. Then call Hawks Motorsport again if it still doesn't shift into reverse.
Then drive the hour home defeated... unless it does magically work, in which case celebrate with beer and we never speak of this again.

Truthfully, I hope it works.

Nah it came strapped down to a pallet so I don't believe it was bent at all. But the "rubber cup" that the ball joint rests in was disintegrated (as seen in the photo). This let the shifter wiggle around rather than feel nice and tight.

I do appreciate your offer though.

Hard to believe since there isn't anything complicated about it. It's a shaft with a ball on the end of it. GTOG8TA sells the same one.

Yeah. I think the stock shifter is actually more complicated.

I agree, swapping shifters shouldn't make a damn difference.

Pisses me off, I googled the shit out of this problem, and there are hundreds of people that have experienced THIS EXACT ISSUE. But NOBODY has posted what it was and what had to be done.

Found a guy that had the same issue as me.

The only evidence they show on camera is the reverse gear with a broken clutching tooth ring. I don't see how that would prevent the shifter from going into the gate.

And there is this guy who experienced the same issue, but he added some more info but no conclusion.

What he discovered was a busted interlock between 1st and 2nd and for whatever reason, the only thing it affected was entering reverse.

Smurf it. Disable the reverse lock out, roll foward at 1 mph, jam it in reverse.

Make sure the "AUTO TRANS" fuse in the under hood fuse box is good and fully seated (don't use Chinese fuses; they only cause problems).

I had this issue awhile back, I used to just muscle through the stiff spring for awhile to get into reverse, takes quite a bit of effort even with 2 hands. Then found out about a spring mod from a mustang forum, where you change the internal spring with one that has about half the tension. It's more of a work around then a fix but it does work if your lock solenoid stops working. Search google "t56 reverse lockout fix".

i found a spring just now on ebay under "Soft Reverse Lockout Bias Spring Tremec T56" although i'm not sure if this is for the same issue or not as there is no mention in the description.

Thanks for all the tips & info!


I went to the shop and swapped out the aftermarket shifter and using a screwdriver as a shifter the transmission went into reverse. So the after market shifter I was using was the issue all along.

I reinstalled the stock shifter and ordered a Lou's short stick to attach to it.

Feel like that’s my fault for suggesting it. Sorry.
I guess that’s China for ya.

Edit. To be sure I can get it in reverse with the trans out of the car sitting on a jack.
I can see where the clearances are pretty tight but.
