T5 in Camaro / Firebird Archive


By Joe Palomina on Sunday, June 28, 1998 - 10:31 am:

Hello....

I'm wondering how difficult it would be to convert an
'81 Z28 from the existing T-10 to a T-5, and what would
need to be done? I would like to have a higher top
gear on the freeway to reduce RPM and improve mileage,
which is killing me at 13 mpg. The car is running with
P275-50-R15 all around, 3.42 differential, and the
current T-10 has 3.42, 2.28, 1.46, 1.00 as it came from
the factory. What would be done to make the T-5 fit?
Also, does it use a VSS or a gear drive for the speedo?

If T-5 wouldn't work I would like a Richmond 6 spd.

Thanks for any help you can give....

I have a 1986 Camaro iroc z-28. My problem is the transmission. It was originally an automatic 700R4 but I have replaced it with a 1987 T-5 from a 305 TPI Firebird. all the parts are interchangeable but I dont have backup lights or a speedometer because mine is cable ant the T-5 is Electronic. I need to know if there is an Electrical plug thatwill plug into the harness for the automatic shifter so that I can use the reverse lights and be able to start my car. Any useful information would be appreciated. thanks.

To ZAK: The backup light switch can be wired manually from your existing switch on the T5. The problem is not with the backup lights but with the neutral safety switch in automatics. You really need to get both wiring diagrams from both applications to make these corrections effective.

I'm looking for a T-5 transmission. I found a 84 S-10 being parted out. The guy claims that it has a T-5 in it. How would I be able to tell if it is a T-5 or not?


By Paul Cangialosi (Admin) on Sunday, October 25, 1998 - 06:48 pm:

To Warren S. Derbridge: Simple T5 Identifiers are 13-52 XXXX casting numbers on the case. Usually ID tags are held on the tailhousing bolts.

Is there a book available that describes detail by detail how to rebuild a T5? If so what is the name and where can I buy it.

Thank you,
Florence


By Florence on Thursday, February 11, 1999 - 01:34 pm:

I have a T5 transmission in my 84 Camaro that is currently STUCK in 2nd gear. I have tried to engage the clutch, but nothing happens. I was wondering what might be wrong with it. I think it is the linkage. Please help!

Thank you,
Florence

I am looking for an '88' or newer T5 tranny for my 87 camaro ready to go within a reasonable price range, please e-mail me back. Thanks for any help you can give. TJ.

I am looking for blueprint of a T5 tranmission for a 91' Firebird 305. Please e-mail either where I could find them or a copy of them if you could. I am missing 5th gear currently. Thanks


By Dave Coffey on Wednesday, March 3, 1999 - 10:29 pm:

I have an 87 IROC, and just put in a mild 350, the transmission was acting funny before and now it will not engage into 3rd and 4th gears. It has a new centerforce clutch and was done at a shop. I would like to rebuild it or get some advice on if i should drop another one in, or get the tremec 5-speed with the conversion kit. please help?


By Dale Swink on Saturday, March 6, 1999 - 07:20 pm:

I have an 85 Camaro w/V6 and a T5, I want to put in a 400 small block, will the bell housing work for the V8?I have a M-22 to replace the T5 with, if I can't use the V6 bell housing is there a kit I can get so I can mount the hydraulic slave cylinder to the tranny?


By Francis Hawley on Wednesday, March 10, 1999 - 10:07 am:

I currently rebuilding my 84 pontiac Trans Am with a 305 engine, and the original transmission fried on me (T5).
I found another t5 but it's from a 2.8 liter firebird.
the input shaft is a 13 or 14 spline, the problem is locating a 10.1/4 inch clutch to fit the 14 spline. The original transmission had a 26 spline input shaft.
GM does not make a clutch plate this size for that spline. To replace the spline is expensive. In Canada
Finding a T5 out of a 305 is imposable locate at a recycler.
Other than buying a rebuilt one, again very expensive,
can you suggest anything


By Derrick Johnson on Thursday, March 11, 1999 - 01:21 am:

I’m dropping a 350 with a T5 tranny into a ’85 RX7. I almost positive the overdrive gear in the tranny is .74 and the stock rear end in the Mazda is 3.909. With those gear ratios I’ll be pushing around 2800 RPM at 70MPH on the highway. I’m aware that this isn’t at all good for a lot or highway driving. So far I can’t find anyone that can cut me a custom set of gears for the rear end. I was wondering if there was any way that the T5 overdrive gear can go from the .74 ratio to around .55 ratio, to help get the RPMs down, or if something like this is at all possible? Any help would be greatly appreciated.

I am looking for a t-5 transmission for a 85 firebird..or if you can, please direct me to someplace that i may purchase a cluster gear and input shaft gear for my existing trans...If anybody can help please email me at fixyorpc4u@aol.com


By GLeal on Tuesday, April 6, 1999 - 09:18 pm:

Is there any difference between the T-5's that came in '95 and older V6 (60deg) and '92 and older V8 F-bodies and the 5 spd in the 96 and newer 3800V6's? I would like to use a 5spd out of a 98 Firebird 3800V6 on a '94 3.4L Camaro, would this work? I have seen the trans behind the 3800V6 and it appears to be much the same except for possibly the bolt pattern to the bell housing is different..? Thanks.


By Slupo on Monday, April 12, 1999 - 08:21 am:

I'm having a problem with my t-5 (world class?) tranny.
It's in an 89 Firebird GTA w/305. The problem is this;
Gears R, 1 to 4 work perfect. When I shift into 5th
(shifts smoothly) and release the clutch on the highway, I begin hearing a vibration sound around
2000 RPM coming from down below. I can also feel it
slightly in the shift knob. when I put in the clutch
and shift to neutral (still travelling around 100km/h), the noise presists and becomes higher in pitch. I'm wondering if the Steel stabalizer plate
mentioned on this site would fix this problem. If so,
consider it sold!...p.s. The clutch and release bearing
are brand new!


By Bobm on Sunday, April 18, 1999 - 08:31 pm:

I have a t5 from a '84 Camaro with a 305. It is going to be installed in a '73 Camaro with a mild 350 (built to the early '70's 350hp 350 spec's). Is it possible to update this T5 to World Class standards by using your rebuild kit? I understand the World Class T5 has an updated input shaft, an updated gear set and can handle far more torque in comparision the T5's in the early Chevy T5's.


By Troy A. Messick on Sunday, April 18, 1999 - 09:01 pm:

I have a '69 Camaro that currently has a TH350 trans. The whole drivetrain is original and pretty much shot, so I've been thinking about converting to a manual. Anyone have any idea if a T5 will physically fit? I can do all the tunnel & clutch linkage changes, I expect I'd have to get the driveshaft shortened and make some "adjustments" to he crossmember, but anything else? Anyone done this on a 1st gen??? Any help appreciated!


By Dwayne Cripe on Wednesday, April 21, 1999 - 03:54 pm:

What is the difference between a T5 and a World Class T5?
Assuming the WC T5 is better, can a T-5 be upgraded to be a WC T5?


By Ryan Petty on Saturday, May 29, 1999 - 08:36 am:

I have a 1984 Z-28 w/ the L-69 305 H.O. and the B-W T5
tranny. It has done fine behind the 305, but I am planning to do one of 2 things in the near future:
1) stroke the 305 out to a 335 which will produce 301 hp at 4700 rpm and 381 lb/ft of torque @ 3700 rpm; 2) drop in a crate 350 w/ somewhere between 350-400 hp and about 400 lb/ft of torque. Before reading your info. on the steel stabilizer plate, I had planned on
dropping in a Tremec T5 or a Richmond Gear 6-spd. or a
T-56 out of a 4th gen. Z-28. Would my original T5 hold
up to the increased hp and torque of my options if I
were to rebuild it to World Class specs. using the steel sleeve, etc. or would I be better off just dishing out the extra cash for one of the other trannys
I mentioned instead of taking the risk of the T5 turning loose after a few blasts down the 1320? Thanks for any info. or advice you can give me. Please e-mail me your response if possible. Thanks again.


By Riku on Monday, June 21, 1999 - 06:35 am:

I have a 86 model T5 for GM applications. It is
slowly losing the synchros on fifth gear. Do your
rebuild kits beef the tranny enough to live behind
350-400 ft/lbs smallblock? Does the stabilizer
plate help any? Are there any "how to" instructions
inluded in the rebuild kits, or where could I get
them?


By Paul Cangialosi (Admin) on Saturday, June 26, 1999 - 03:33 pm:

To Riku: The stablizer plate helps "beef of the transmission as stated on my t5 page www.5speeds.com/t5.htm. Kits do not come with any instructions just as an engine kit from TRW comes with none. If your drag racing this trans it will not live period.


By Randy on Tuesday, July 20, 1999 - 07:47 am:

I would like to purchase a WC T-5 for my Camaro.

I understand that the WC trannies only came in 88 or later V-8 powered Camaro/bird.

Problem is that our local boneyards have pulled all of the trannies and have them on shelves.

How can I identify the WC tranny from the non-WC tranny if the year of the tranny is not known (tag missing etc.)

In other words - how about a list of casting #'s or other such identifying marks to differentiate between WC and NON-WC trannies.

If I can find one of these trannies I will purchase your rebuild kit and bearing stabilizer so I won't have to go through this again.

Thank you for your help
