Not hard but IIRC you need to remove TB, air filter box, battery box to have full working access if you want to intercept it before the cooler. BUT I think you can just work from the bottom IF you intercept the flow AFTER it comes out of the cooler. TIP, buy a foot or two of transmission hose from auto store (its cheap). Save the OEM 'pre-bent' hose b/c they cost an asinine amount, in case you want to reuse it.I will also look into installing the inline filter. Doesn't look too hard so far.
Million dollar question: does FORScan have a TCC override function to lock or unlock the clutch on demand? The idea is to see when RPM drops, does clutch slippage occur? At stop (when low idle occurs), can you manually override the clutch to lock it?From what I observed over a brief drive monitoring session, it does engage/disengage as supposed to - see the OSS graph (orange). The big flat space between 100 and 128 is idling at a stop.
Is there anything wildly abnormal, that should further be investigated in your opinion?
I would greatly appreciate any advice on which parameters to group on this graph that would help to understand what is going on.
Also, I tried feeding this data into chatgpt4o and, to my surprise, it outputs something that now actually makes sense, although, the recommendations are very generic, i.e., "note whether a change in LPSA LPSB correlates with gear shift, look for random spikes on OSS, etc".
That is the idea!Seems like some control of the transmission solenoids is available. Buttons are inactive because currently the car is not connected.
For the record, this is an activated version of FORSCan on PC with vLinker OBD2 cable.
I'm now doing the research on which one controls the clutch.
And when I figure this out, the plan is:
1. drive until warmed up, monitor the TCM
2. stop in D, wait till RPM drops below 600 (~590..605 in my case) and vibration occurs
3. activate the clutch solenoid and see if the vibration goes away
If the vibration goes away - the torque converter is to blame,
if not - then something else.
Am I getting this right?
With all due respect sir, I do believe you are overthinking, whatever is going on with your vehicle.If the vibration goes away - the torque converter is to blame,
if not - then something else.
