c-6 no first gear

got my tranny rebuilt last week by a local guy.....transgo kit few other internals......installed it went threw the gears no ist gear.......tranny guy came over tonight pressure was 220 in all gears but 1st it was 350.....took the valve body with him so we will see whats up tomorow...strange the pressure was that high

Yes i agree, should not of been that high. If was a transgo kit with modulator connected pressure should be around 130-150 and with low vacuum under load may go 180-200 max.

He f'ed up on the VB

hopefully he fixs his screw up.......

well the tranny guy came back tonight with my valve body and installed it. Have all gears with 220# on his gauge.....off to the track tomorrow night maybe i can make a pass after 9 when things settle down .......wish me luck... hopeing for mid 10s.....probably high 11s cold track

That 220 seems awful high on the line pressure. It is very easy to reduce that pressure by shortening the spring on the main regulator a little, or simply using a different spring.

ill relay that message to him and see what he says......what could be the outcome of too high of pressure......ill post what he said when i ask him about it to night leaving for the track right now to move staging around a bit expecting a huge car count....bracket stuff is done if they have lights they can run sticker cars....

did 2 shake down passes.......taking it easy..... 3rd pass left off idle went threw gears evertything fine.....4th pass left farely hard threw 1st and 2nd about 5000 rpm tranny let go..bounced off the rev limiter coasted around the corner at top end no forward gears...just reverse......well we will see if the tranny guy stands behind his work

Man, that sucks. What did it run?

Sounds like its time to get Mr. Merkl to build you up a trans.

I have my spare trans for sale, it's a Broader Performance fully rollerized/manual VB 1000 HP wide ratio C6. It is being freshened right now, but when it's done it's got to find a new home,

Let me know if you could use it.....

Greg

i would take your tranny in a heartbeat but the shipping would probaby be twice as much as you want for it... i really appreciate the offer....im going to give the tranny guy a chance he is respected with car guys here . i work at the local track here and im sure he doesnt want the back lash of people asking why he didnt fix my tranny......it was cool had 25 guys pushing the car on the trailer....didnt have to winch it on good bunch of guys.....

tranny guy told me the front drum is cracked.....oh well .....for a slow street car i seem to be having a few problems ....street car shoot out this weekend i think ill enter .....need the seat time....

If it is cracked around the snap ring groove?? Look to lowering line pressure while it is apart.

on the edge of the drum its all cracked off like the edge of a bowl the lip is gone and ground down Ill try to put some pics up for you guys tommorrow.....ran out of time tonight ....just have one header and fill with trans oil.....going racing on friday if it doesnt snow....

Yeah, C6's have a tendency to crack the forward clutch drum right on the back edge happened to me twice. Getting a 4140 steel one from TCS products, that should fix it! Bit pricey BUT!! Especially getting sent down under!!
