Tranny Questions

[gectek]

I have been through 42 pages of the PPM page and i have found numerous posts on trans swaps and all that sort. So the 4t6x trans WILL bolt up to the 3400 engine and it will work in the GA, it is just alot of work. Second, the 5 speed(or 6) is a very good idea for those who want the joy of shifting up and down in stop and go traffic. Also there is no manual valve body for the 4t4x trans and why would you want one in the first place. Also manually shifting the trans can lead to all sorts of problems, one of the being the fact that doing that will"freeze" the trans in one gear for too long, leaving undue pressure in the trans without it being metered and having a threshold time of switching the solenoids due to the transition of the shifter from one gear to another. This can also harm the valves by possibly lodging them sideways in the bore, or gouging the bore. and it can also lodge the check balls into the pressure plate. ask me how i know.

so why are so many people giving up on the 4t4x and wanting the manual swap or a 4t6x swap? has anyone done any research to find what all is offered for this trans, or any trans that can be implemented on this one? how many of the answers given are actually founded on proof or fact and not just heresay, or something someone "heard from someone else"?

You already know how I feel seeing how you will be building a new trans for me. lol

[gectek]

yes and thanks for the free plug...lol

yah, but i have seen numerous posts on this. i really would like to know withough getting flamed at or starting an internet grudge match where everyone has to show off their internet penis

[bballr4567]

I think the main reason is because plain stock this tranny has horrible thresholds at least from what Ive been told. Most people cant get past that part.

[slowbird]

I'd really like to do something with the stock tranny. I don't like it at all. It's fun having the car chirp going into 2nd or just having the convienience of the Auto.

If I knew of a place that would rebuild my Auto, and they were well known and trusted...and it didn't cost more than swapping in a 5-speed....I'd do it.

As it stands now I don't know of anyone locally that can rebuild my tranny that I can trust.
For now I may just go somewhere and have them replace the filter and fluid and install a Trans cooler.

[gectek]

well im not going to say anything right now, but you can ask bballer about performance rebuilds on the 4t45. im looking at doing a few things in the next few weeks, just keep your eyes open for it

and ill keep u updated on how my tranny holds up

[bballr4567]

Yea Matt some of the stuff that John will be offering are really impressive. Itll be sweet once you get your tranny back together and get it on the track.

[gectek]

yah i hope so

[slowbird]

I'm sure John knows what he's doing...but he is not local...so a rebuild by him is NOT an option.

I'd like an Auto rebuild...it'd be nice...and not to complicated since you just toss it back in...you just gain much more performance from a 5-speed swap...and IMO, 5-speed is much more fun.

[TA^Guy]

My biggest complaint about the 4T45E was that the shifts were too sluggish.

However the 5 speed auto in our Explorer make the 4T45E feel like a performance car. Talk about slow shifts....ekkk!

Maybe I'm just spoiled with a fresh 4L60E in my truck with Corvette servo. :shrug:

[slowbird]

I admit the PCM and firmer shifts makes the Auto alot easier to live with...but the auto does too many things that upsets me.

Upshifts when I don't want it to...downshifts too far at times.

I love the convienience of it...stop and go traffic is great.

Thats about where the benefits of the 4t45 end for me.

[gectek]

well i do fix all of the shifts that are mechanically and hydraulically related to sluggishness, and alot of that was due to a bad thought process by GM, which they fixed for the 02 model years and up. but i do that upgrade as well. if you want awsome shifts and a higher specific TQ input/output then i would look at an 03-04 trans to be certain. they worked alot of the bugs out and that is the best place to start. like i said the rebuild isnt for all, esp if it is a daily driver, but it would take you almost as long for the 5 spd swap anyway.

[slowbird]

Yea...I heard they fixed a few things in the 03-04 tranny...it makes me a little less nervous when I make the car chirp 2nd.

...but I'm still nervous enough that I do it very rarely. :O :P

[gectek]

just keep on it til she blows then ull have a good reason for the swap...lol

yah, well i used to do that alot and only started having probs at about 130k mi, so that isnt too bad.

drive it like u stole it

personally, For about 99% of the people out there, a stock tranny will hold on fine, and even then, if thats not enough, a simple tranny cooler with some PCM programming can do wonders. NOt until you start breaking your tranny often should you bother with rebuilding and building up a 4T45 or swapping to a larger or beafier 4T65

[slowbird]

I think if you are breaking trannies you are well past the point when you should have thought about a tranny upgrade.

You should be thinking of a swap or rebuild before you're stranded on the side of the road/track.

If I was starting all over I would have just rebuilt the auto tranny I think im 9 months into working on my manual swap all the time dedicated to finding the parts.

[slowbird]

9 Months?!?!

What parts are you/Were you having trouble finding?

[Burger]

I have a 2000 GT. Automatic. I want a manual tranny.
1. Is that possible? Clucth pedal, trans, etc installed. Match the holes
2. Any pics?
3. Any places that can do the work?
4. Parts hard to find?

[Ralph]

the clutch pedals and shifter assembly. Almost no junk yards around here had a donor car. I just decided to say screw it paid a crazy amount for axels and on the misc parts they i needed. Only thing left is mounts and a clutch.

[ChevelleSSLS6]

would any parts from a 4banger GA manual fit?

[gectek]

that is what they are talking about, but i dont remember which bolt pattern fits the v6, either the eco tec or the qaud 4, but i really dont care too much for the manuals...

[Ralph]

you have to mix and match stuff from the J-body and the 5th gen GAs I posted most of what I learned in some tread on here. If you search 5 speed parts it will probably come up.

[DomestikDemon]

Just so all know, the auto GAs (99+ maybe older ones too) come stock with a tranny cooler. Its a one piece unit combined with the radiator

[chewy]

imagine how much money one of our sponsors would make it they would find out how to do the 5 speed swap and then sell the parts to do it...... hint hint hint for our sponsors out there

[Ralph]

honestly I have said it before rather then swapping a 5 speed I would just buy a 5-speed GA and swap over my stuff. If I hadn't already worked so much to find these parts I wouldn't be going through with it.

thats true, even my brothers 93 grand am has one (3.3) and my 96 (2.4) has one, but I think a seperate cooler gives it better cooling.

[red_se]

Getrag 282 trans(crazy hard to find)
all manual parts from a 99+ grand am
3.1 flywheel .ext

Simple yet not for this kind of swap people need lots of details but no adays you don't have to look far for them

[slowbird]

The hardest part with the manual swap is getting the OBDII system to accept it all.

[Joe_Beach]

I've got an 04 3400 and since the 28000 mile mark when i got it it always felt like it slipped between 2nd and 3rd gear and between 3rd and overdrive. Last week it got really bad when i came off of a red light it wouldnt go into 3rd or overdrive so i drove home at about 30mph the whole way and drained the fluid and changed the filter and refilled. It shifted fine for the first 5 minutes of the test drive then it wouldnt go into 3rd or forth again unless i take all the torque off the transmission by releasing the gas pedal.

[Adam88]

So i have an 04 grand am, Headers, high-flow cat, 2.5 piping back to a flowmasters 80s, cai, mp racing tune and I don't chirp second at all, due to being 4 door maybe? =( Oh and I blew though my 4t45e trans already, they said a gear shot though my casing... If there was someone that could build up a 4t45e I would be all over that!!! Even if its out of state, thats what ups ground is for eh?

[DomestikDemon]

Pretty soon Ill be doing more work on my car....the 5-speed trans/motor/clutch are all together and in the car, but still needs mounted correctly and drivers side axle needs completed....
