will a t5 hold up to a 350 tpi im buying a 350 tpi motor from hawks and i was woundering if my t5 would hold up to it and if they would bolt right up some one help me |
Re: will a t5 hold up to a 350 tpi The short answer is not no, but HELL NO. The long answer is that it will for the most part if you drive the car sensibly and don't race it or do burnouts in it. Honestly where is the fun in that? The stock World Class T5 was only rated to handle 300ft/lbs. of torque. Even a stock L98 puts out 340lbs. of torque or so. The T5 just won't handle that for too long. At least not if you are actually enjoying the car. You have a few options here. You can either upgrade to G-Force internals or swap the transmission for a TKO or T56. Each swap has their own sets of challenges and extra parts that are needed to do the swap, but it can be done. If you intend on putting some real power to the ground you'll NEED to do something about the stock T5 trans. There is a reason why GM never paired the L98 and the T5 together as a factory option. |

Re: will a t5 hold up to a 350 tpi Yeah I know the T5 CAN last. There used to be a member here that had one behind a fairly heavily modded LT1 as I recall. That was back when I first joined. I don't know if that guy is even still around. I guess it would depend on your performance goals and how you drive the car. Personally I couldn't resist the occasional burn out and track use. |
Re: will a t5 hold up to a 350 tpi Well, I would say you have two routes: 1. Save some money and then sell the T5 before you install the L98 motor and get a different transmission. 2. Install the L98 with your T5, baby it to no end while you save up the cash for stronger. Either way I would highly recommend a stronger transmission. Selling the T5 will offset the cost a little bit but not a whole lot. Keeping the T5 and buying outright will give you a backup transmission in the off chance you have to rebuild the other one. Out of the swap options, my personal taste it the T56 from the 94-97 Camaros/Firebirds they handle 450 tq and drive like a T5 with an extra OD gear (.5:1) Heavier, yes, pricey, kinda. My T56 and bell cost me $1400, while the rebuild on my T5 was $1000. |
Re: will a t5 hold up to a 350 tpi Personally I prefer the T56 used in the 2004-2006 GTOs. I prefer the gear ratios and they shift a lot smoother. |
Re: will a t5 hold up to a 350 tpi for the amount of money for a t56, you can run a tko-500 or tko-600....WAY better gear ratios than a stock t56 and stronger (and you don't have to worry bout burning out the stock conical synchros). Richmond makes an aftermarket t56 that good as well. The tko has the best ratios in my opinion (the tko-600 with .82 od is my choice personally), but I wouldn't bother with a T5, you'll find a couple people that have run them without blowing up, but it's a ticking time bomb, and I don't know about you but I'm not that lucky. |
Re: will a t5 hold up to a 350 tpi My problem is that installation of both the TKO and the T56 seems like a huge pain in the ***. |
Re: will a t5 hold up to a 350 tpi Yes and No. As long as you have all the parts, it's a matter of taking out and putting back in. About the worst part about it is correcting the shifter placement. If you want a REAL pain in the *** take one carb 80's Monte Carlo, drop in a fuel injection motor, then put a T-56 behind it. Now THAT sucks. Those never came as a manual, and have no return line for the fuel injection, and have a lot of fab work. After working on that and robbing what parts I need from my 92 RS I can see how easy a T56 swap is in a 3rd gen. (However, the RS is manual already) Going from auto to T56 would be a little more difficult, mostly because of wiring some things up. |
Re: will a t5 hold up to a 350 tpi HELL yes.. I Have a WC T5 behind my HSR 350 no problems it's in the 500HP range I see why drivers smoked there T5.. the main weak link is that bogus stock shifter upgrade to the PRO 5.0 short shifter <> night & day difference... 2nd weak point is the 5th gear bearing retainer upgrade with the billet retainer |

Re: will a t5 hold up to a 350 tpi Lmao, best laugh I had all day was that Arnold Schwarzenegger comment. GET TO DA CHOPPA! |
Re: will a t5 hold up to a 350 tpi well then I'm very lucky http://www.youtube.com/watch?v=hLJPXJPSlfw have you shifted a T5... with a stock shifter <> even behind a stock motor!! it will not go in 3rd.. say good night to the trans.. that 5th gear factory retainer is tin and allows to much flex & play... that was my first concern with keeping the T5 behind this motor I know i'm making.. alot more then 300 foot pounds <> explain that.. bring your car over and i'll put this T5 to use LMAO the terminator is BACK ROFLMAO |

Re: will a t5 hold up to a 350 tpi yeah the T5 case flex is the cause.....I'm no experts, but remember something about the distance between the main bearings is really far, and even with upgraded shafts and gears, still flexes. Some people do get lucky and never have a problem, but I personaly have blown up a few behind 305's. It it worth doing a swap in the end, but does take a bit of time to complete the swap, and some small modification needed, but nothing too hard. |
Re: will a t5 hold up to a 350 tpi I'm looking at the TKO 600 myself. The T56 is nice but I don't want to cut my transmission tunnel to install it. Not because I think its hard, but because I don't want to hack up my car. |
Re: will a t5 hold up to a 350 tpi the only problem with the tko's is you have to run an adapter plate, adapter pilot bearing, and different shifter.... |

Re: will a t5 hold up to a 350 tpi I've been running a WC T-5 behind my 355 for over a year with no issues and I have never been one to "baby" it. I've tried to grenade it a few times just so I'd have a reason to upgrade but the little T-5 keeps hanging in there strong. |

I'm just waiting to split the case and shoot gears out should be spectacular!! |
Re: will a t5 hold up to a 350 tpi I would not highly recommend a WC T5... but lets face it most of the people that state they exploded this trans on a stock 305/350 have to be Gorilla shifting or left the stock pathetic shifter on and missed 3rd there are many people including myself in the 500HP / 400+ TFP with no issues there are many stangs that get there T5 in the 10's |
Re: will a t5 hold up to a 350 tpi While you can probably get by with a WC T5, again I don't recommend it. While this isn't a T5, this is a great example of what CAN happen when your clutch/transmission fails. http://www.youtube.com/watch?v=hJtJUVyEyYY Figure out how much transmission you need and go a step beyond that. |

Also, no offense to anyone, but what the hell does the shifter have to do with how much torque the trans is going to hold? and flexible that you can not shift into 3rd ( is the most problematic ) now if you are @ WOT 3rd wont go.. you force the shift what do you think would HAPPEN???? there are many people that have way beyond 300HP / 330FP that use the T5 with no problems.. I don't promote the T5.. but it,s held up for me so far.. and others PS I have smoked about six 700 DOG 4 the last one was built with every known part. manual VB & trans cooler with my previous motor around 400HP it did not last 8,000 miles |
Re: will a t5 hold up to a 350 tpi That's odd given how strong the 700R4 can be made and how weak the casing on the T5 is known to be. |
Re: will a t5 hold up to a 350 tpi well.. if they are so weak... Why has mine not disintegrated |

Sabb.. absolutely nothing..It's the fact that the stock shifter is so weak and flexible that you can not shift into 3rd ( is the most problematic ) now if you are @ WOT 3rd wont go.. you force the shift what do you think would HAPPEN????

Re: will a t5 hold up to a 350 tpi it's not that it's hard.. the stock shifter is so flimsy.. it will fight against 3rd when under pressure.. the short throw is just a preference... a strong shifter is REQUIRED |
Re: will a t5 hold up to a 350 tpi When you are making serious power a strong shifter is a necessity. Short throw shifters are just more pleasant to shift and you may or may not like that. Even so most people do and the stronger shifters are pretty much all going to be of the short throw variety. I can't stand the stock shifter. The thing is too long and sits way too high. Its goofy looking and uncomfortable. I've never messed with a stock T5 shifter beyond the context of a junk yard but I can't imagine that they shift well. |
Re: will a t5 hold up to a 350 tpi I agree with the Eiffel tower T5 shifter I cut my Pro 5.0 3/4 more it could be worse the ZF 6 speed is taller.. and you punch the radio.. on a light shift |

It's taken years for me to learn this, but man handling the gearbox and forcing the issue is not the way to go. A light touch is required. I love a solid shifter, but unless the throw is silly long, I'm not keen on short throws. I find they make the gears too close together from side to side so it becomes tricky to select the correct gear. Personal preference I guess, I've just never found the 6" throw that hard to deal with. Anyway, back on topic a bit. What was that bit about the 5th gear retainer? How difficult is it to replace? |

Re: will a t5 hold up to a 350 tpi thats a joke my freinds dad had a 355 with a stock t5. he beat the hell outa that car. the motor went before the trans(after 15 years of beatings) |
Re: will a t5 hold up to a 350 tpi I have not installed my billet retainer yet.. it looks pretty easy.. and highly recommended and no I was shifting correct.. I'm telling you 3rd.. on a stock shifter.. under load should not be just right, lighter, more firm, lil left ,lil right this is how the T5 gets smoked my Pro 5.0 perfect every time in 3rd |

Re: will a t5 hold up to a 350 tpi here is a link for the 5th counter gear retainer http://www.5speeds.com/t5.htm I found mine on ebay <> best deal offer .. for 15 bucks less |
Re: will a t5 hold up to a 350 tpi i like my stock shifter over the short throw my buddy was tryin to convince me forever to put one it after a while i gave in after about two weeks it came back out and went on craigslist |
Re: will a t5 hold up to a 350 tpi I would have to say... you are the first.. and only person... that would want to do that the stock shifter is clearly JUNK..there is rubber in the middle and flexes and who wants the shifter that long.. it's not a TRUCK <<>> |
Re: will a t5 hold up to a 350 tpi 2 Attachment(s) Since we are on the shifter subject of the T5, I thought I would entertain all of you with what I found in my 84 Monte when I bought it. Sorry if it's blurry, only have a camera phone Attachment 413662 Attachment 413663 Now THAT's an ape hanger! |

Re: will a t5 hold up to a 350 tpi now that is artistry>>> how can you complain with that one of a kind workmanship.. That is a great find. I guess you showed me... how much do you WANT for it I have to have it LOL |
Re: will a t5 hold up to a 350 tpi 1 Attachment(s) Lol, the whole thing was exactly one half of a full assed job. That's what you see in the second picture, EVERYTHING MUST GO! But, not wanting to give up as much of my Camaro I could, I robbed a lot of little things to make it feel more at home, seats, center console, etc. Here is what it's coming together looking like: Attachment 413655 |
Re: will a t5 hold up to a 350 tpi Has anyone put in the Hurst shifter for T-5s? Heres a summit link http://www.summitracing.com/parts/HUU-3915032/ I've driven a 4 speed with a hurst Shifter and it felt rock solid. |
