this is what I found this am

What is the 1st code? Cannot see it but your transmission is slipping. Tires cannot effect the speed between the axle and the driveshaft. Drag tires could cause an ESP/ABS fault due to front and rear tire slip rate.

Do you have an aftermarket trans cooler to go along with your high stall torque converter?

99lightning

no trans cooler p2563 p2560 thank you Ec for a quick call back but they said those codes are from a turbo car

99lightning

my car even with weistec tcu you would have to clear code before racing with drag tires but this tcu tune now as soon as I put the tires on it went into limp mode hope to get it sorted or it will just be a car for street

blackbenzz

Do you get the same codes on the street or this only happens with the drag tires on? What is the overall tire diameter difference between the 2?

2000UZJ

I had two different diameters on it and it went into limp mode (abs/esp off) with no speedo after about a mile at highway speeds. ABS intervention under light braking too. Was not fun

99lightning

yes only with drag tires the only thing I could think of is with the 306 gears made the wheel speed ramps up quicker but all jerry did was lower my shift points so it would shift better. it was fine before I would just clear codes to be safe before I ran in staging lanes. now even during the burnout it can go limp. maybe I should take it to the track and clear it with star before a run instead of my dashdaq

EREBUS

This happened to me with using Toyo R888 285/35-20's. Esp Codes along with transmission irregular ratio codes. Dyno mode, for some reason, will not let me drive the car? (it would actually go into limp mode and not shift gears with codes stating transmission is slipping!)

We attempted to pull the wheel sensor/esp fuse and the vehicle would not get out of gear. lol

love the car hate the trans makes me want to get a cts-v and tune it myself. hate to retire it on my 11.48 run but may have to.

blackbenzz

Don't give up There were a bunch of V's at my rental friday including the newest v3 running 11.3 They are monsters and plenty of aftermarket for power

99lightning

yea im just use to fixing this crap myself. no reason if this car hooks and shifts it wouldn't run a 11.30 11.20 it shifts and carries on all the time and still traps 121mph

blackbenzz

Can you get a drag setup with similar rolling diameter as your stock setup?

EREBUS

Same here. I've been driving the vehicle with the tires hoping the vehicle will adapt. It's kinda weird.........because it is adapting? Esp light not longer flashes when normal breaking. In fact, no more Esp or transmission codes with a few hundred miles of highway driving and multiple resets.

2000UZJ

I put maybe 100 miles on mine. Never really felt safe and didn't like it. It looked pretty stupid having a tire that was 2" taller in the back. lol

I will saw. Kumho Optimo tires are quite fun to roast

whipplem104

There are no adapts for different wheel tire sizes.

i heard also if the trans temp is too cold the car can get messed up it did sit for almost 4 hours.

Hulk

Trans has to get to operating temp
Do you run in dyno mode
I ran in dyno mode

I have gotten the code also at the track but cleared it with my dashdaq and no issues

EREBUS

Yeah, my setup looks a little redneck at 3/4 inch taller. lol

99lightning

yes always dyno mode. I doubt trans was up to temp then I gave the drag radials back to my buddy I may tomorrow put my 26 inch tall qtp tires on and try a few launches to see what happens.

EREBUS

probably not with a 2" difference between front and rear. maybe it's due to my tread being worn down enough to be within guidelines. that is why I said it was "weird"?

mankaran

hey, nice setup,

What wheel and tire setup do you have. I also have cls55. Thanks

https://mkultra-electronics.company.site/ trans shifting problems solved this man can even change tire size in tune if you give mm of tire height.
