GTA or Trans Am?

I am not sure how to read the vin to tell if its a GTA or t/a. I have been seeing pics of controls on the steering wheel. mine does not. and there a date on the hood of 88 I think. I can tell my car was a re-paint, and some of the body parts look put on by a novas back yard car guy. and how do I tell for sure of the motor. 5.0 or 5.7 is it in the vin like the 2nd gen cars? here a few pics.

Re: GTA or Trans Am?

Its a trans am.

You need to check the RPO codes in the console, and you'd be looking for Y84 code. Read this:

Re: GTA or Trans Am?

Nice car!!

As Arrow said, you need to see the rpo Y84 on the SPID sticker (inside the center console lid). You cannot tell if it is a GTA or T/A from the vin.

But, some hints about identifiying the car. 8th digit of your vin is an F (305). The 350 would result in an 8 at that location in the vin. The fender vents are found only on T/A's (although they could have been changed out). And I believe the car should have had the steering wheel controls if it was a GTA. Finally the dash pouch should also say GTA.

However, it can be a challenge after more than 20 years to find cars that have not had changes done for one reason or another. It all comes back to Y84.

Hope that helps,

Gary.

Re: GTA or Trans Am?

I think it is a gta, just has the wrong fenders and steering wheel, by the vin its a 305 car, u need to get the #off the block to see it its the right motor, good looking car. Engine bay looks really nice

Re: GTA or Trans Am?

If you want to know what size engine you have in, besides the VIN, there's a number on the block, but you may or may not be able to see it. Your other option is to put her on a dyno. The wheel you have is from a standard Trans Am, you have fender vents like a Trans Am, and the map pouch on your dash has only a phoenix, where GTAs have "GTA" embroidered on them. Black crosslaces came on Trans Ams...GTAs all got gold. The ONLY indicator you have that it may be a GTA is the gold tail bird...and that's the easiest swap to make. I'm betting it's a standard Trans Am but a GTA clone.

Re: GTA or Trans Am?

At one time, you could go to your local dealer parts dept, and they run your vin, *AND* if it was a true GTA, then that option code would pop up and state that it was a GTA because parts listed for it would be highlighted with the Y84 option code, but I am not sure now.........

Re: GTA or Trans Am?

Sadly Cliff, it only seems to work for Canadian cars. I've run both my GTAs and confirmed Y84. Any vin I've tried to run for American cars come up with nothing other than decifering the vin.

Re: GTA or Trans Am?

I tried that also Cliff for both my car and my wife's car so I could get a complete list of RPOs and they're clear text descriptions. I believe 91 was the cutoff when I tried last. :|

Re: GTA or Trans Am?

This service will tell you if you have the GTA Y84 option or not:
http://www.gtasourcepage.com/forum/s...ad.php?t=50539

No other way to know for sure since your RPO sticker is missing. Everything else is strictly a guess.

As it sits right now, you have more signs pointing toward being a Trans AM than a GTA based on the appearance leaning more towards Trans AM specific items.

Reason why the title states GTA or Trans AM is because the prefix VINs are the same between the two. The DMV does not know the difference between a GTA or Trans AM based on the VIN.

Re: GTA or Trans Am?

you guys are scaring the hell out of me ! my gta has the dash pocket with just the gold bird, i have the same steering wheel as 4 speed, no rpo, i had to buy and install all the badges, "because the car was repainted"..........it has been wrecked, and repaired, has a rebuilt/salvage title. i'm waiting for the paperwork from PHS, but from the way you guys are talking, that isn't going to tell me if my GTA is real or fake. i think I'm gonna be sick...........

Don't take it too hard if it's an authentic TA George. There were fewer TAs built in some years than GTAs. Mechanically (drivetrain) it's identical or nearly identical to a GTA and it has the same great body shape. As far as I know my car has all the performance options available on a GTA (TTA excluded) except the aluminum driveshaft.

Re: GTA or Trans Am?

Did all GTAs come with aluminum driveshafts?? Mine is steel, but everything else is GTA-accurate... *scratches head*

Re: GTA or Trans Am?

The aluminum driveshaft came with the 1LE rpo code for the Players Challenge Cars (Camaros and Firebirds). They can be found quite regularly on e-bay. I put one in my first GTA. Did I notice a difference? No, but a post on TGO from someone who did the swap at the track said he picked up 0.3 s. I keep thinking I should put them in all of my Firebirds just for the heck of it.

Re: GTA or Trans Am?

If i had to take a guess by looking at the vin and rims and also since the paint has been redone(but looks very sharp), The steerig wheel (aftermarket stereo)its a TRANS AM. But i could be wrong, defintly check into general motors for seein if it the real deal. But with so much originality taken away from this sweet ride id hate to say its prob not what ur wantin to hear. I had this fear but my badges were in original state and the motor needed rebuilt and all the parts matched for a GTA including the nice leather interior and radio control steering wheel. It had never been repainted(still needs paint). The rims are original. If you would like to make this more authentic then look on the web for GTA parts and make this the real deal.

According to option numbers on this site 796 of the 1990 GTAs had the aluminum driveshaft.

That's what I love about these cars. Just when you think you have it all figured out, there's always something new to learn.
