Well I had my car towed to the transmission shop in Philadelphia, PA (about 25 minutes from my house) and the mechanic pulled the trans out immediately. He told me that the car's transmissions shift sloppy and the way they are built from the factory are horribe. He's had his share of LS4 cars in his shop before. When he started my car in his garage with the doors closed, my exhaust set off an alarm that was parked outside the garage door which i thought was hilarious. He told me that he will rebuilt my transmission and it will have a shift kit in there and a transmission cooler. Real cool guy and said he loves these LS4 cars because they are true sleepers. All in all everything will cost about 1600 dollars and should be ready by this Thursday right before the holidays

 

What shop on Philly? I'm ready to get my trans fixed, torque converter can't make up it's mind. Either engage or disengage, make up your damn mind!!!!

 

Better have that shop order the TEP valvebody and a Sonnax converter valve or you'll be having the same problems again, eventually.

 

Listen to the man.

 

sounds like a great shop!! ill be in the philly area in two days, unfortunately i wont be driving gxp, im flying.. rental car is a g5.....ugh

 

its called Riz Transmissions on Tansdale ave i guess thats North East Philly. I really cant wait to get this thing fixed. I miss hearing that exhaust rumble when i start it up and roar when i step on it

 

Torresdale ave. That's 10 mins from my house, I'm gonna swing by after work and talk to them about my trans, try and sneak a peek at your LS4

 

hahahaha i can dig it brother. yeah they do good work there. my boss refered me to them. he did however recommended that i NOT get a shift kit on this car because when he rebuilds it, it wont need a shift kit. my dad told me not to get a shift kit either but i think its because he's old school and doesnt believe in shift kits in these cars today

 

Yep. Replace the converter valve, pressure control solenoid, valve body, and add a TransGo shift kit with a extra steel and clutch in the second gear clutch pack. If you feel like tuning then I'd also swap out your gears with for some 3.29's. Transfer cooler obviously. Other then what comes in STD. Rebuild kits you should be good to go. Goodluck!

 

Man.. excuse my spelling and crap I'm using my phone lol

 

Thanks man. Im gonna go back up there probably tomorrow and see whats been done and etc. I just dont get why these cars crap out the way they do

 

Quoted for truth. Be sure to go with Sonnax valves and not factory GM. If you don't, you'll be sorry.
