Upgrade from .63 to .74 5th Gear?

OK, so there's a bearing howling in my T5; it's coming out for a rebuild.

I'd really like to upgrade from the TBI .63 OD 5th gear to the TPI .74 OD.

My understanding is those gearsets are no longer in production. Is that correct?

If not, can anyone recommend a source?

If they are out of production, what about sourcing them used?

What other upgrades should I do? I've read about carbon fiber synchros and upgraded 2-3 shift forks, but have no idea how to source them.

Can anyone help?

Re: Upgrade from .63 to .74 5th Gear?

Yeah, I started with Google a couple of weeks ago. Dozens of sites claiming to have the fix for T5s inherent weaknesses. No way to tell who is selling snake oil, and who is not.

Also no one addresses the 5th gear swap I want to do.

So, I came here and asked. I've been here 13 years, dude. Kind of a dick move to post a "google it" link to my reasonable questions.

Maybe make some calls to the people you googled then.

Re: Upgrade from .63 to .74 5th Gear?

We should probably just shut this whole forum down.

Why bother sharing information with fellow 3rd gen owners?

It'd be a lot simpler if every question posted on here was just auto-answered with: "Google it, dumbass".

Re: Upgrade from .63 to .74 5th Gear?

I mean, what kind of an idiot thinks there's any value in going on to a forum populated by people who have exactly, or nearly-exactly the same car as he does and ask questions in the hope that some of those members may have been in the same, or a similar situation and could offer some advice more specific, and less narcissistic than one might find by calling every result from a Google search?

After seeing your post count and looking at a few, it's pretty clear you sit at your computer all day long and comment on nearly every post on here. Maybe that explains why you haven't had time to build a T5 in the past 15 years. I don't think it's a coincidence that you joined this forum 15 years ago. We now know what's been eating up your time and keeping you from rebuilding T5s.

You posted two links; D&D, and Halon (before you went back and deleted the links).

I'd already looked at D&Ds site, and talked to them on the phone. No bueno.

Here is EVERYTHING Halon has for GM 5 speed transmissions: http://cart.hanlonmotorsports.com/5-speed-transmissions

Yeah

Ever hear of Roseann Rosannadanna? I think she's a lot more applicable here than blazing saddles.

I asked a question; you replied with a link to a google search for T5 rebuild kits. It was an insult.

Re: Upgrade from .63 to .74 5th Gear?

Sorry to side track you here & feel free to go back after Tony when I'm done. I find it puzzling that after all of the work you've done to your car (and the money you've spent) that it's a full second & 4 mph slower than my original car was with 80k miles on it & without a single modification from stock. The slip all the way to the right has the best time & to my knowledge, this is the only time the car was ever at a track.



BTW, there are several guys here on the board who are doing same/similar strength builds as you & if you contact them they can likely help. Sofakingdom is also very knowledgeable about the T5 but will likely tell you to swap in a T56, which would be my suggestion as well - money better spent.

A) I don't see what this has to do with the original post.

B) Except for the headers and exhaust, my L03 Is stock. The ultimate TBI mods are absolutely worthless when it comes to power; I've documented that on a dyno.

c) If you have a close-to-stock L03 TBI 3rd gen hat runs 14.50s, you have the fastest one on this site.

Re: Upgrade from .63 to .74 5th Gear?

Looking at your sig, though, that LB9 probably offers a clue.

Maybe you should have looked a little closer before hijacking the thread?

Re: Upgrade from .63 to .74 5th Gear?

Not like my life is any of your business but the reasons I quit building them is because the 6speed came out, I grew up, a career change plus a family. All that kinda takes time away from side work.
Unlike some people, I don't mind trying to be active here and not just when I need something.
Like I said, a lot of the places I used to source parts from, are either gone, names have changed or they moved on to a better (selling) trans.
All of Hanlons complete web site is pretty much blank. A lot has changed.
Unless G-force has anything, I guess used is all you can do since nobody seems to offer parts for them anymore.

Re: Upgrade from .63 to .74 5th Gear?

Sorry about the hijack, just an observation based on your signature, which it appears you want everyone to know.

If your goal is a better & faster car - you may want to go a different direction. If you're asking for help, you may want to take a better tact.

Re: Upgrade from .63 to .74 5th Gear?

I'm quite happy with my car, thank you very much. It runs a second-and-a-half faster than it did when I bought it, and I'm quite pleased with that.

There's no braggadocio in my sig. See, if you put a lot of info about your car in your sig, then you don't have to go and repeat that information every time you post a question. If you post a Bruce Springsteen lyric in your sig, you might have to.

And tact? Brother, you need to get over yourself. You came into this thread and hijacked it by smugly criticizing me with an apples-to-oranges comparison you were either too dense, or to lazy to even know you were making.

Here's a little secret for you. My car is on the quicker end of the scale of cars similar to it on this site. Yours isn't. Before you come in out of the blue and start pompously sneering at someone, you might want to get a little quicker.

You SURELY ought to do that before you start the lecture.

Re: Upgrade from .63 to .74 5th Gear?

Don't worry too much about it Sean. If you think you got lousy service in this board, check out my flop post in the same board. Sometimes it happens. I don't think it's specific to Transmissions and Drivetrain, but rather coincidentally one of the very few times I received zero help on Thirdgen.org.

Re: Upgrade from .63 to .74 5th Gear?

G Force and Astro both offer replacement gearsets for the T5 but it is a lot more expensive, closer to the $1500 pricepoint. If I were you I would just be on the lookout for somebody selling a rebuilt one, somebody on this forum was selling one for only $500 not too long ago. That is cheaper than buying new gears and a rebuild kit, along with labor costs. Looks like there are also lots of new and used gears on ebay right now.

Re: Upgrade from .63 to .74 5th Gear?

Ordering parts is sometimes easier when providing a VIN at a dealer.

Similarly . . .

There is a listing of all T5 service tag numbers on the internets. They're formatted from the Borg Warner system as 13-52-xxx.

If you narrow down which box you want the 5th gears from, providing that tag # to any Tremec dealer should allow them to quickly show stock (or OOS) for the mainshaft and speed 5th gears.

The T5 has a lot of aftermarket support. I don't know if the 5th gears you want are in stock as Tremec parts, or aftermarket. But one online vendor shows pricing of about $320 for both.

Saxondale, did you start reading and taking notes yet?

Re: Upgrade from .63 to .74 5th Gear?

a full second & 4 mph slower than ... without a single modification from stock
Seems to happen ALOT with people that modify TPI cars, esp 305 ones...

I have nothing to offer the OP however. I used to know quite a bit about that, sources and part #s and whatnot, maybe even where some used ones were at one time in my garage, but suddenly forgot everything while I was reading all his posts. Quite a shame I'm sure.

Really? Wow.

What has happened to thirdgen.org?

You go ahead and keep your information to yourself, Brother. At some point, I'll figure my problems out ...... you'll always be you, though.

I figure I'm getting the better end of that deal.




PS .. for, like the third time ... mine's a tBi; not a tPi.

Apparently, reading comprehension drops as churlishness rises

Sorry you had to deal with that, Big Dog. I'm not really sure what's going on here. I've been a member here since 2003, and for the most part, have found it to be a community of enthusiasts helping each other. I haven't spent much time in Transmission and Drivetrain, though.

I don't know if what we're seeing here is exclusive to T&D, or a bunch of trolls are just having a bad day. This sure isn't the thirdgen.org I'm used to.

That is cheaper than buying new gears and a rebuild kit, along with labor costs. Looks like there are also lots of new and used gears on ebay right now.
Yeah, I've looked at the G Force and Astro gearsets. There's been a lot of discussion about them on here.

My original plan was to drive my car, and do all the foundational mods before I did the engine; suspension, brakes, etc. My exhaust is a good example: SLP 1 3/4" shorties, dual cats, a 3" mandrel-bent intermediary pipe, a Flowmaster 40 and mandrel-bent 2 1/2" tailpipes is huge overkill for a 305 TBI car, but is just right for the 383 I had planned.

As part of that 383 plan, I was going to go with the T5 direct-replacement T-56 Rockland Standard used to offer. The price was great, and it was upgraded enough to handle the kind of power I planned on making.

My plans have changed, though. I'm just not interested in making that much power anymore. I'm going to drive my 305 till it dies, then replace it with an L31 crate motor with a cam upgrade.

That power level, along with the fact that I don't ever power shift, or do burnouts, etc. puts me in kind of a middle ground, transmission-wise. There's no way a T5 could handle the power my planned 383 would have made, but an upgraded T5 could probably handle a mild 350.
