4T45E Rebuild

[Tdunk]

Hey guys i was just wondering if anyone on here has rebuilt their 4T45E transmission. Right now i was looking into LSD and Cryotreating it. Is it difficult to rebuild it and any info and guides on rebuilding one would be appreciated. I also found this page for the Limited Slip Differential http://www.engineered.net/eplsd.htm

[gectek]

i explained alot of this to you, it takes alot of special tools. i wouldnt cryo treat it, that would be very expensive. shoot me an email at john_ginter@hotmail.com and ill give you the logistics of it ok

[Tdunk]

Okay i just figured i could work on this myself guess not.

[gectek]

well im def not saying you cannot work on it, but it takes quite a few special tools and they rather expensive, about 3 or 4 are over $150, and it takes a good working knowledge of how the trans works itself, and what damaged parts to look for

i am not calling you incompetent and im not just trying to sell my services, if you wanna do it, knock yourself out and if you need suggestions or advice, im here, i just find it easier to let someone else who has more exp than i do take the load, and i have rebuilt 2 so far and one was mine, it has lasted almost 40k miles with no probs, but im building a stouter race type trans to handle more power and be more durable.

and just as soon as i get mine pressure tested, then i plan to offer rebuilds for at least the 4t4x trans, and if i can do enough research, maybe the 440t4 and subsequent 4t6x as well. and it will be a customizable build, you get what you want and see the cost for the upgraded parts as well as any wear parts that have to be replaced up front, the only uknowns will be broken or worn parts that arent normal wear parts, and the shipping.

cryoing isnt that expensive and it wouldn't be a waste though i would look at the cost of titanium nitriding as another possibility

[gectek]

well i would think it would be, because it really isnt needed as far as anyone knows. its just like the koleen steels. they are an option, but expensive when compared to stock steels, and are actually less strong than the stock steels, and raybestos does all their testing with the stock steels anyway, so there is no need to buy them.

it is more exp than just staying stock and seeing if that will hold first, and i didnt see on any of the websites what the quote would be for the entire trans, but i know an engine is exp, so i figure roughly that same amount

I really dont feel like getting into this here cause I dont know when I will look at this thread again but....

as far as I am concerned there is ALOT more that needs to be done the 4t45e trans other than update the parts GM has over the years.. cryo and nitride treatment is required to ensure part life and also there are a few parts that must be made custom from better materials than used in a stock trans...

if all you do is replace the normal wear parts, do all the GM updates, and install a set of raybestos clutch paks.. then you arent doing much more than a stock rebuild which wont hold very long on a car pushing more than 250 (even with an EP limited slip diff) esp if it sees ANY track time

all the 4t45e's that will be avail from MP Racing will be capable of handling 400+ TQ@ 5500 rpm ... come standard with LSD, your choice of final drive ratio, , and a PCM programmed for the new final drive ratio. The PCM will also have upgraded trans pressure and shift tables to take advantage of the build....

[gectek]

just like i said i make no claims on proven perf, but u told Tdunk that it would hold 550, now you are down to 400? anyway i know you are still working on it and trying to prove the numbers, that great, but im not just doing what you are thinking, and also TEjohnson off gagt didnt do as much to his and he handled well over 300, so that speaks for something. anyway i told them if they want yours, great, if they cant afford yours or dont want an all race trans, im an option, if not then just go to you or rossler or the one milzy is supposed to be making. i have no prob with that. i am offering another choice and i didnt go knocking your trans, so id appreciate it if you didnt do the same to me or try to downgrade mine on this thread. like the guidelines say, if you have a personal beef with me or have something to say against my work, PM me. I am not your competition, i am just another possible vendor.

and also there is a prob with offering a generic tune pcm just for the trans mods, and we both know that, i wont go into specifics, but the trans should only be pushed so far, even a race trans breaks and when it does, it is more $$$ to build back up

and also mine will have alot more than what you described, but its a choice for them, most of them wont want a diff ratio due to the DD that most of these cars are, and they wont understand that until it is explained to them, maybe ill make a thread on that, as well as tire and rim usage for the effective ratio also

Okay this entire topic is going to be deleted. First it went from useful information to a full out trans competition. This trans was supposed to be useful information not..... this. This thread will be deleted shortly.

Tdunk has a knack for misquoting me as we are testing the trans at 550 right now... we have already proven the trans to hold over 400 and we still havent broken it so we can only claim up to 400+ for sure.

I didnt come here to bash on you in any way shape or form.. in fact i think that its great that you will give people an option I am not willing to offer... I only wanted to state the fact that to achieve max potential there are other things required to be done. Reading your posts you come off like you know that you have a proven setup that will hold the gobs of power dunk claims to want to make.. but the truth is that you will need to cryo and kolene treat parts as well as having some made... the setup todd is using has been reworked a few times and there is no proof of how long his trans will last at his power levels (only time will tell).

I had no idea that Mike was going to get into trans stuff too ... oh well just more shit I would never buy from him.. lol

I dont know where you came up with the idea that trans tuning was the same as engine tuning but I can assure you that you very well can make a generic set of settings to accomodate the upgrades done to the trans such as gear ratio, pressure tables and shift time tables...

In any case I only posted info about the product that my Co will be releasing since it was talked about between you and Dunk....

I really wish you all the luck in the world with what you are doing and hope that your products are the quality that you say that they will be since many wont be able to afford a trans from me.

settle down there dunk.. I said something and he took it the wrong way.. I explained myself and now I am done...

I have nothing againt gectek in fact I really hope that he does like he says and offers an affordable option for those who cant afford trans from me...

the more quality parts available to the n-body guys/girls the better...

[Tdunk]

..... this topic is being closed i dont enjoy you sitting here and putting me down as the bad guy. All i did was search for info and ask questions......btw you said tested dude and you one again seem to think i want this 2000hp trans i dont. I need something very reliable over 300hp because what i'm putting together will either snap in half or wear out my curent stock trans. Hell i''d probably be okay with a well maintained stock 4t45E

[El_Diablo]

wow, he hasn't put you down at all really, you miss quoted him and didn't put the correct facts out there about a product ive been telling you is still in the R&D stages and therefore he cant put out any real numbers yet anyways yet you continue to set your price at 3-3.5k and 550hp garunteed... he said hes testing and has no price yet...

oh and might i remind you that your the one who said you wanted the trans in the first place? and wanted to make 540hp on it? hes not pushing his trans on you so calm down


oh and gectek, he never started bashing your potential product, he layed out some facts, real facts... dont BS people and stop trying to get into a fight

so are we settled now? damn... calm down people and just get the info out, its not that hard

[Tdunk]

............. show me where i talked about marks products. What i said to you guys isnt even on this forum please stop bringing it up. I barely said anything to him about marks trans other than 2 things 550tq and 3k. THATS IT. I never misquoted. and how many more times do i have to say this I CHANGED MY MIND FOR A 540hp TRANSMISSION. None of you know what i want ans quit saying you do. I changed my mind a long time ago!!!!!

[bszopi]

I think someone has a misunderstanding about how much Todd (tejohnson) had done to his tranny.... I think he's on either his 3rd or 4th build right now. And that is in a short ~2 yr time frame.

Honestly, this thread sounds like a bunch of girls getting their panties in a wad. Hell, it appears that most of the conversation has taken place either on a different forum, via email, or in person.
