11p transmission 4l60e holding gears
Re: 11p transmission 4l60e holding gears
I posted my upshifts/ downshifts so you could see what the relationship looks like between the two.
My shifts were also hanging on.
Is the tune OK?

Quipt4it just saw your picture of your up shift down shift I will compare post up what I ended up with today only really played with up shift when I get home and on pc. Thanks
Re: 11p transmission 4l60e holding gears
Thanks to a few guys on here and your help i finally have the l67 running pretty decent in car.
To whoever asked about the tps working correctly. I put ignition on and pressed the accelerator slowly and it shows zero at closed throttle and 100% at full throttle.
here are 2 logs
one is normal driving
and the other is some close to full throttle run i done when checking AFR's and shifting of trans.
Quipt4it Thanks for your transmission upshift and down shift map/table. They work good. Tho the trans does not kick down at all nearly when say doing over 60kph it just feels like it stays in 4th or 3rd.
It will kick down say at 40kph full throttle to 1st which is good.
2nd and 3rd very lazy to kick down also but they will if you press throttle down enough.
For normal driving at normal traffic pace and in and around the side streets etc it shifts up and down great up till around 60kph or so. Once you up around 60kph or more it gets very lazy to want to kick down a gear at all.
Basic info on car
l67 swap into vr
vr 4l60e with corvette servo
Shorty extractors stock cat and 2.5 inch straight through single system
Stock airbox
Ported blower stock TB
Iat tapped into lower intank manifold. 2 bar gm Map sensor pickup of nipple on front of lower intake manifold next to were i mounted tapped the iat sensor

Re: 11p transmission 4l60e holding gears
Glad you got some action
Maybe on those 'lazier' downshifts, up the downshift column numbers a bit.
Go in 1-2 km/h increments and see how it goes
On the 4-3, I didn't alter those, as I never use 4th lol. I keep my 'stick' in 3

Re: 11p transmission 4l60e holding gears
Thanks quipt4it
I understand the upshift table and how it works
but i cant get my head around downshift
Down low i see when throttle is closed i under stand how it works say when coming to a stop (slowing down 0% tps) it wont shift down to 1st till 12.88kph say
But later on say around 60kph or so and im in 3rd or 4th gear how does it work?

Re: 11p transmission 4l60e holding gears
You need the correct L67 tables as the shift points and TCC lock/unlock speeds are quiet different to n/a V6 models. See

Re: 11p transmission 4l60e holding gears
Out of curiosity, what converter are you running?
Re: 11p transmission 4l60e holding gears
The downshift will occur when the criteria of both the TPS and speed are met.

Re: 11p transmission 4l60e holding gears
immortality standard vr torque converter on l67 flex plate ring gear
I also just remembered i dont have any TCC lockup
I also remember reading somewhere that my 95 model vr has some different bits inside the trans than the 94 model vr and later vs vt trans ?

Re: 11p transmission 4l60e holding gears
PWM for lock-up?
