sorry. forget that video. i wrote about 2 problems (questions) in that post. the video is for the KR thing that i got answered. it wasn't a problem.. it was more of a curious thing that i was wondering why it was doing it. if i don't want what was happening in the video.. i'll have to get a different PCM or get a tuner myself and fix it. i'm on to this tranny issue now.

i'm hoping to just take off the side and put in a new boost valve and pressure control solenoid and hopefully that cures it.

This isn't pulling the drivetrain. Drivetrain is technically the engine and transmission. However say you pulled the trans. Then you'd rebuild the whole thing because the labor involved in pulling it is worth the $200 for the master kit with clutches etc.

If you are only pulling the side cover as you mention, and you plan on doing the valve body cures/upgrades as we've discussed. And you did a shift kit in the accumulator, then you will have done everything possible without pulling the rest of the trans apart. At that point you'd replace clutches, seals and the input piston thing that always wears.

sorry for the confusion Bill. my mistake about the drive train.. i want to just take the cover off. what can i replace when i take the cover off beside the boost valve and pressure control solenoid? hopefully those two thing cure my problem.
 
Re: '07 GXP - Tranny work being planned...

bill.. i went to a dealership down and got some info and what not. plans might be moved up and i could get this done sunday most likely done by my dads professional tranny worker. in the cities.. it'd cost me over 400 bucks to have a dealership. says it'd take 3 hours to do. is this something people would say i should do or is that just outrageously expensive? it seems to me like it is. I need to order a pcs for sure and a boost valve maybe too.
 


Re: '07 GXP - Tranny work being planned...

Question. First, planning on putting in a PCS for sure this weekend. But I've been told that you have to take the whole valve cover off to do the boost valve? any info on this? I'll be going to the dealership tomorrow and asking them what really needs to be done. Just thought i'd ask on here and maybe save my time and some other guys time if i could get an answer.
 
Re: '07 GXP - Tranny work being planned...

Bill, where is your how-to on doing your drivetrain pull/tranny lowering? i can't find it in the page.
 
Re: '07 GXP - Tranny work being planned...

i saw that one.. but bill did a different one.. one with him just lowering the tranny rather than pulling the whole works out. he was doing work on a drivetrain and i cant find it anywheres again..

I believe because of how the retainer clips are installed holding both the PCS and the boost valve that have to be accessed from the back side of the valve body. I'm not 100% sure but the PCS might be able to be done with just removing the oil pump. Boost valve on the other hand I think is a different story.

i got a print out of everything in the tranny. the boost valve clip is in the valve body and the pcs is a clip on the outside and should be able to just pop out with nothing else needing to be taken a part. another quick question. bill puts his engine board.. support what ever you wanna call it.. his board he uses to hold up the engine.. 'parallel' with the car.. instead of across it on the strut towers.... is that the best and safest way to do it? or should i go across and use the strut towers? also, how do you lower the tranny down per-say... just leave the chains a little lose so it can fall down a little?
 
Re: '07 GXP - Tranny work being planned...

I've seen it done both ways and it really doesn't make a difference. If you have the jig...sure use it but I've always done it as it looks in Bill "How To"

And yes, EPC can be accessed without taking off the valve body. Boost valve on the other hand is not and you'll have to remove the valve body.
 
Re: '07 GXP - Tranny work being planned...

Went back and read a few of the posts about your trans.....IMO you're putting and TON of time and effort into just putting a band-aid on the problem. If the car is still drivable keep on driving it and put the time, effort, and money that you're about to spend into the full rebuild.

I totally agree with Dave @ TEP and Bill

i've heard different.. but again.. they weren't experts as people would call Dave and Bill telling me that this would probably fix 95% of my problem. This may cure the problem or it may not. I don't have the time nor the money to do a full rebuild right now. If they puts a 'band-aid' on the problem and cures it for the next year or so.. great. i might be ditching the gxp anyways this summer. I gotta start here and learn as i go. Even though everyone thinks i need to do a rebuild... i don't wanna do a rebuild and spend all the time and money in doing it. i'd rather have the next guy do that.
 


Re: '07 GXP - Tranny work being planned...

It suck when you dont get the time to fix up your cool ride, but i guess your planning on selling it for something else? If you ever get the time or money i suggest getting the TEP tranny, people on the Impala forums have done that and they used there "Better" Tranny and now are running 300+ HP with no problems. Combined with the trans cooler too. Hope things work out for you bro.
 
Re: '07 GXP - Tranny work being planned...

But guess what though even if you get something in RWD and you get more power youre going to have to do something with the transmission eventually its a fact of life man.
 
Re: '07 GXP - Tranny work being planned...

Did the tranny work today.. took all day. Posting more later tonight with pictures.
 
Re: '07 GXP - Tranny work being planned...

Well everyone, got the pcs in there in everything seems to be going good so far. its cured the 'problem'..... for now anyways..

drivers side all taken apart ready to be lowered down.


heres one of the engine mounts, if anyone was curious.


those thing were a PITA to get off from there. You have to get them from the inside of the front of the car.

take the front lower grill off to get to them.

there they are.. them bastards... royal PITA!



got the sub frame off and lowerd and taken out of there.


cover and axle.
Note: i did put a new axle seal in there too, it was leaking a little bit already.



cover taken off.


PCS taken off.


New PCS


everything cleaned up and ready....


but wait...


we had to snap the 2-3 shift solenoid while putting the cover back on.. piss...

so at that point I stopped taking pics i guess. The guy ended up going home and getting a new part and got it in there and we ended up lowering the engine and everything another chain link and everything went on better. threw everything back up in there and good to go. i didn't get any pictures of how i chained everything up to hang it but it was kinda how Bill does his. Except I did like a tic-tak-toe board over my engine bay and the right side of the engine was fine to chain on to. chained onto the eye hook mount or whatever it is in the back right and then onto the front right dog bone. and on the left we had to put bolts in holes with chain to hold it.. sorry i didn't get any pics. reply and tell me if anyone is really curious and i'll try and take some pics of where the holes are. but everything went great the only thing now is my steering wheel is out of center..

thats going straight down the interstate.

so i'll need to align that back up sooner rather than later cause its quite annoying like that.

let me know if anyone has questions about what i did and i'll try and help. over all this was a royal PITA and i don't know how anyone would like to do this for 40 years (thats how long my dads buddy has been doing this crap).
