I have smoke tested the intake and I haven't found any issues, Have also have checked the throttle body. It seems like the initial change from park>gear has a large increase in the idle target maf which then is causing a raise in RPM, 9 times out of 10 I get a P2110 code when the RPM rises. Also want to confirm if increasing Idle Airflow in Park/neutral (auF0032) will assist in getting Idle air integrator closer to zero? Idle.teclog

Hi all, I replaced my throttle body on the weekend just in case that was an issue however i still cannot get rid of this code when putting it in gear. This only happens on a cold start and if i attempt to put the car in gear it will just go into limp mode (p2110). I have posted a log of it happening, i have added a startup closed loop delay timer which has somewhat helped, however it still happens occasionally. If anyone has any insight would be greatly appreciated. FYI the car does have a set of TBRE cams in it. p2110.teclog

Okay i will get this updated and report back with how it goes. Thanks for the help.

All shift pressures are standard in normal shifts, only upped for sport mode under high low/rpm, however the line pressure for low load is at 7.6 in 3rd and 4th, would it be worth lowering below stock for the shift pressures or try lower line pressure l?

Hi All, Since this issue i have had to get a new set of clutches in the box. My Adaptations prior to the rebuild are as per the attached snip. with only doing 500k's on the box with the new clutches i am having harsh downshifts from 4-3 and also Reverse. I am just wondering how long the learn process usually takes as even after the 500k's my current adaptions are: -39 mBar -250 mBar -182 mBar -190 mBar -490 mBar this is a built box with 6r80 internals and extra clutches. @hjtrbo I saw some posts you have made regarding adaptation temperatures and reducing values to ensure the box is within the adaptation threshold. I am running a PWR exchanger and my temps usually are sitting around 84-87c. Just wanted to confirm if these are the correct tables relative to the adaptation thresholds.

@Mick What parameter are you logging for tcm slip, as the ones I’m logging are just always zero. thanks!

@Superb Converter isn’t stock and that’s the file the guy who built the box loaded in, would you care to share some changes that have worked for you as I’ve come up empty.

I'm having this exact issue and have been trying to fix it for some time, Are you talking about the circled values?

What Adapts are you logging exactly for this time of stuff?

More than happy to listen to some random shit! Correct, Only happens on the first shit. The next 3/4 shift is fine. Would you happen to know the trans slip parameter on pcmtec for logging. Also applogies for the questions im still learning all this, In my case when the box is warm the shifts are good, I will make some adjustments in ZF01454 Shift 3-4 Offset at the lower temps and see if that gets me anywhere. I did make some slight adjustments to ZF01733 Boost time clutch e, Lowered the time at lower temps but dont feel asif it made a change, mind you im only lowering by 20 so also unsure if that would be noticeable or not.

First photo is the first gear change to 3/4 then a moment later with very similar temp is the second 3/4 gear change. Very different calculated slip times. for some reason it was only logging the trans so all the other numbers are the same. @hjtrbo Thanks for that info mate appreciate it.

If i reduce E Clutch Boost time slightly in the tempertures im feeling the slip could that potentially help, Along with increasing Shift pressure tables 34 on low loads.

Yeah thats the plan, Also im trying to log the Trans Torque in NM. Does anyone know the right paramter to log for this. I tried logging Trans input torque but thats not the correct one.

@BillIm going to take it in next week to see what he says about it. I done a few tests over the past few days in regards to it being temp related, It seems to be the first 3-4 Shift after key on (when cold) is the only time it will slip. After that first 3-4 shift if i slow down then go for another 3-4 shift its fine. Other than that first shit i cant fault the box at all its been really good.

Its properly built with extra clutches.

Box was built just under 2 years ago, I have had the issue for the past 5-6 months. Thanks @hjtrbo I will take it back to the guy who built my trans to take a look as its still under warranty.

No i haven't done that. Unfortunately i only have the professional version so im unable to view those parameters. But i will log the temp and find out exactly when its happening. Will playing around with Nominal Slip time (ZF00884) and maximum shift time (ZF01636) be able to help at all?

Hi All, I'm having an issue when the car is cold and i put it in Reverse/Drive idles will raise up then the car goes into limp mode and throws the P2110 code. If i start the car and put it in reverse straight away it wont happen, Only if i let it sit for like 10-15 seconds then put it in gear ill get the code, But even if i do put it in reverse straight away by the time i reverse out of the drive way and go to put it in drive it will throw the code then. The car does have a aftermarket cam if that makes a difference. Is it okay to zero off the P2110 in dtc controls? Or can i raise auF0517 to a high number to stop it from happening? ,Thanks

I'm actually only gettiing this slip when the box is cold. I cant find the exact table to up line pressure with lower temps to try and fix this issue. Would you by anychance know which tables i should be looking at? Also could my numbers be out of range at all due to it being a 6r80 Built box.

Hey mate, thanks for the information. I have attached a photo of those parameters on the logger. these numbers did not move as i was driving just stayed the same. Can send log if you would like.

Hi, I'm getting some slip in 2-3 and 3-4 down load mainly and on light-medium loads. I turned down ZF00900 (Nominal slip table) down by 50 on all light loads, Went for a drive and the issue had gotten alot worse. Does this stuff need time to re learn in those areas before i start to feel changes? Thanks.

Hi, still chasing a solution to this issue if anyone has any insight would be great. I have attached another log file. Cold Start.teclog Cold Start 2.teclog

Ctd? I can try send another log if that one isn’t working.

Hi All, I have an issue where my idles are fluctuating on cold start. They do come normal towards the end of the log, Not sure where i should be looking to make some changes for this. On the Log it starts at around 129 and the idles are smooth by 250 (Time) Hoping i've logged enough to be able to diagnose the issue please let me know if i need to log something else. Car does have an aftermarket cam and is on E85. Any help will be greatly appreciated here. Cold Start.teclog

okay makes sense thank you. How about Road speed? everything im logging is always way under what im actually going.
