whats up guys i have a 06 with full bolt-ons and cam..The car has a ss4400 yank converter.the trans has upgraded clutch packs,rear has a 3.42 gear. I been having some problems with the trans going into limp mode.. It started from doing pulls from a roll..if i flashed the converter while it was at low rpm it would throw a code and the trans would lock in the gear..(im pretty sure 3rd gear)

Last night i did some pulls from a dig, the car launched great and went through the gears until 3rd..the car shifted into 3rd gear and than wouldn't shift into 4th..at the top of 3rd i noticed the check engine light came on so i let off.. i turned the car off and did another pull from a stop with the check engine light on.. the car went through the gears fine but wouldn't shift into 4th again..it hit the rev limiter...

i haven't pulled the codes from last night yet but the first time it happened i pulled the codes and this is what they are.

P0700 transmission control system
P0716 turbine input shaft speed sensor circuit range performance

i was told that the converter is too big and the trans is getting confused because of the turbine speed.. I was also told that i can just delete the codes so they wont pop up anymore and the trans won't go into limp mode. I plan on restalling it this winter to something a little smaller.

Would deleting the codes be a good idea or will it put me at risk of something worse happening..

Thanks guys!!!

 

I would lower the RPM and MPH shift point from 3-4 and see if it shifts then.
If so then you will need to fine tune your shift points

How does it feel with the 4400 in it? Sure would like to see how it feels... I though about trying a 4k

 

If you're running NGK plugs they might be the issue because believe it or not (and this came directly from a tech at NGK) they can cause havoc on your electrical system including the TCM.

As for turning off the P0716 code, you can't so that won't be an option for you.

A 4400 converter works fine in a 6L80 as I'm running a 4000 Yank and love it.

Who did the clutch pack upgrades to it and were they a reputable shop?

 

Interesting on the NGK.. gonna have to pull a plug..I bought the car like this...

the car was built by Jeremy Preston out of horsepower sales of Florida..a vendor on here..I haven't gotten a chance to talk to jeremy about it...could it be something with the trans tune or maybe a sticky solenoid??

 

If Jeremy tuned it then I'm sure it was done properly. If switching out the plugs doesn't work then I'd look at having that speed sensor replaced as they do go bad but fortunately can be replaced without having to pull the transmission.

 

Are there any write ups on changing the sensor and where i can order one from.. I did a few searches real quick and didn't find anything.. I'm gonna try getting the car into my tuner this week and have him go through everything and check out the shift points and such.. I'm gonna pull a plug tomorrow as well and let you know what i find.

 

It seems that the code pops up a fair amount of time before the shift point..I would say prolly halfway through the gear the check engine light pops up..

I've only done 2 dig pulls with the 4400 and it feels great..now if only it'll go into 4th lol

 

Not that I'm aware of but the part can be ordered from the dealership.

 

Mikey, just to let you know my car doesn't shift to 4th in the quarter. Maybe with the 3.42 gear yours does but try it at the track and see. You're car is pretty much built for the 1/4 mile.

 

yah mine needs to go into fourth..

 

Plugs are AC Delco 12621258

found this puppy too

 

Hey Guys,

I sold this car December 2011 and it has since had 3 owners including the current owner so I can not be certain as to what changes have been made via parts and tuning etc. I never had the Tranny Codes here when I was racing the car but things could of broke or been changed with the previous owners as well. The car left me with MSD wires and NGK Plugs but your last post shows taylor wires and AC Delco Plugs.

In your PM you mentioned you would take it to speed inc. They are a highly respected shop and will be able to address anything. You have my cell number and shop info, Please call if I can help.

Thanks

Jeremy Preston

 

Wow sold three times in 6 months.
Hope you get it figured out

 

Thank you for the reply jeremy!!

I took the car into speed today and had jim look it through.. my buddy that works there just called me and said jim took it out for a test pull before he touched anything and it pulled the code again..he than fine tuned the shift points and did 4-5 more pulls with no codes... I changed the wires back to MSD before jim got it..he said if the code comes up again that it can either be a bad sensor or the trans is starting to go..

Im taking it to the track on friday and hope for the best..

Jeremy would you be able to email me the tunes?? And would the race gas tune be compatible with 100 octane?? Im not familiar with the c10 race gas you used..

 

Sounds like some good news Mike. Friday we rage.

 

Let's hope so dankeeekeeeeee..

 

Picked up the vette and took it for a few pulls..the first pull was good,shifted fine..than did another dig pull and it wouldnt shift into 4th again.and stayed in 3rd gear till I shut the car off and turned it back on..I had jim flash it again and the same PO716 input shaft sensor came up again and also a cam position sensor code came up..

he cleared the codes and i took it for a drive..during normal driving the cam position sensor code came up again.

 

might potentially have cam bolts backing out..getting a rattling noise when i rev the car up to 2000-2500..and have the cam position code..today after leaving speed inc, i stopped at the gas station..tried starting the car up and it wouldn't start..cranked for 3-4 seconds..i stopped it and tried again and it started up..than did the same thing when i got home..

Put the car on the lift and could barely see the sensor.. Just gonna have to bring it into speed inc to tear everything apart and inspect the cam bolts..

 

can anyone provide more info on the Trans issue.. I was told i can delete the trans codes with EFI live... But i don't wanna risk deleting the codes and there actually be something wrong.. i been searching high and low for info and can't find much related to the PO716 code.

 

there is a detailed information about dtc codes,causes and solutions in service manual...you can delete the codes but i think your tcm will give same errors again..
