Car chockes and Loose power on uphill
#5
that is all normal that white dust, its from the plasma arcing from the rotor tip , via that gap to the cap tower pins, all 100% normal.
what matters is cap cracks, oil inside, or carbon tracking. Just clean it in soap ans water, dry it and it will be ok. or use carb cleaner inside, this plastic is fuel safe.
4 speed, shifts, 1, 2,3,4, does it shift right?
if the rpm flares that is trans slip, and has nothing to do with engine.
if the rpm does not flare, and power is low, the that is engine power weak.
no the tCM can never tell the PCM to stop any engine. The TCM only auto shifts the box, that is all it does.
if the engine shakes that is misfire, ever try new spark plugs or full tuneup ever? cap, rotor wires, will cure misfire, in almost every case and 10x that if tuneups are skipped, and for sure the 60k mile service points did you skip that? no car runs forever , not tuned up, (spark parts and filters)
if the engine bogs, this is not misfire, misfire is violent, bogging is smooth loss of power, and is fuel mixture related. fuel pressure tops list there.
did you look at spark tips they talk to all mechanics, you look and see if the tips look bad, if yes, they are bad or engine fueling is rich and turns black.
they talk, all it takes is looking at them. removed.

the A/t can fail in many ways. lets talk that..
1": fails to shift up 1,2,3,4 or down, 4,3,2,1 per normal
if it dont shift right, then it glows the CEL lamp and you scan the PCM and get P07xx errors, telling you , I CANT SHIFT right and WHY. all new cars do this too. its not new any of this.
The trans can slip, this is called FLARE, flare means you hear the engine scream (rpm goes nuts) and car can not accelerate , after all slip, does that, like the chain falling of you bicycle, you can go. and pedals fly fast and no go. called drive line slip, this is in the the 4speed, it has clutch packs that can slip.
If it dont up shirt that is TCM , and trans issues, scan it.
if the trans fails to down shift on hills, at it must, then that is TCM trans issues. (or bad TV cable , rusted up or fell off)
so far i have not a clue here if the trans fails, or then engine is week.
the RPM and MPH gauge in 5min work tells you what is going on. the 4wd car has a RPM gauge, all do. with 4wd, use, it.
ever rode a 10speed bike, and had to shift gears/? this teaches you how a transmission works, you must down shift to go up hills,
but normally the 10speed can not ever slip, it is chain drive, and no clutches, but if it had a clutch it too could FLARE, RPM of feet rich way fast and bike slows down.. failure.
this is how all machines move, gears and clutches. in theory its all very simple, watch a transmission model on you tube. see how they work.
Does the engine lack power in all 4 gears,(sure will on higher gears if power is weak)
does it? does it flare.
does it misfire
does it only bog. like pulling dead weight,
a mechanic sees all this in 5 minutes work at a test drive ,somethings I can not experience here. ever.

Try to now the difference from
Transmission gears dont shift right.
and Transmission FLare.
and engine bogging
or engine misfiring
this is required in all cases, to work the correct parts of the drive-line.
also the CEL lamp if it glows running the car must be scanned. (i bet your car is NOT OBD2 car ,like ours) and is OBD1, and you can only do flash codes from the CEL LAMP.
The only scan tools that work in OBD1 (over the counter) is the TECH1 scan tool.
Is the CEL glowing key (it must) and goes out running? and is the OD lamp flashing (means TCM is not happy and most be scanned now)
The PCM will report errors is scanned or diagnostic jumper inserted, (ours work with OBd2 all do , we invented it)
the TCM has its own port, and own jumper and flash codes. (ours works different in USA our TCM reports through the PCM and can be all scanned as one)
the TCM has its own connector and jumper and has flash codes that flash the OD lamp. this is outside usa only this method.

The TCM will report all errors from any of its sensors.
it can also report failures to upshift, after all it does the up shift command to the trans solenoids and if RPM of the tail shift(VSS2) does not drop then the shift did not happen
if the shift happened but the clutch pack slips, the TCM sees that and tells you , it did that.
in the USA only the TCM sendes P0700 codes to the OBD2 scan tool. this tells our mech, the TCM has errors , and the CEL Glows, and OD lamp glows, warning driver TCM errors.
outside USA< the TCM, can only flash the OD lamp. and with flash codes on demand.

This is how it works and is 2 different systems USA and exports.

try to listen an feel transmission shifts. up and down.
learn to count them. 1,2,3,4 and od.
this same on all modern cars, only more gears now.
on hill the TCM sees to events for that hill, actually 3.
1: aggressive TV cable movements, (throttle valve cable)
2: the TPS throttle angles tells same info as above, and is redundant but the TCM can use it to shift.
3: the ECU (PCM) has thing called load, the PCM computes LOAD at all times, a hill is a big load, the PCM tells the TCM hey buddy, big load, and the trans TCM down shifts one gear.
this is how it all works.
learning all this allows you to know instantly what is up, and wrong,
as does flare. flare is trans slip and the tachometer goes real high real fast but not SPEED, that is slip.
if it slips that is all bad bad news.
now lets talk limphome, mode, the ECU has it and so does the TCM
the ECU tells you , this with the CEL glowing and ENGINE sensors failures reported.
the TCM can go to limphome and now skips 2nd gear, this tell you , you are in transmission limphome mode as does the OD flashing same deal.
now you have lots of fact on driveline issues

but first is :
is it engine?
or is a the trans... as in all cars made. the same deal and test drive is the cure.,
as is watching the CEL and OD lamp for odd actions.
