Dokidoki:
hello car gurus I need your expert opinion about my vehicle. I noticed on cold start(in the morning or after bn parked for about 8hrs),the vehicle transmission does nt enter drive(it enters reverse gear easily).it gives a sound similar to bn in neutral gear(possibly it slips to N).
I am able to overcome the slip by raising RPM to about 3+ and it then enters drive with a loud thump.afterwhich the car drives normal throughout the day , selecting all gears smoothly and as appropriate(ofcourse until it's parked for another 8hrs plus nd I av to force it into drive gear again)
I also noticed that when I move to drive gear in the morning and I depress the brakes for about 7-9seconds ,d car shifts into gear with a mild thump nd am good for the day.
I also have bn able to overcome the early morning problem by allowing the vehicle to warm in the morning for about 10minutes(when I do that car shifts smoothly from start)
I have changed my transmission oil(T4) and av even cleaned d gear filter with no difference.am yet to scan d transmission but I will appreciate suggestions from experts in the house.
my mechanic here says it's valve body.another one said I shld change d gear while fingers av also bn pointed at gear selector and sensors.
vehicle is Toyota Camry 2003 V6.
I just remembered problem started after I used my battery to start someone's car nd my RPM became low so I had d Mech increase it temporarily till it normalise which happened nd gave me high rpm... though I tried reducing it bt it's still higher than normal(could dt be related to d gear issue I started experiencing afterwards?)

all other car gurus ur advise is needed.

mayor2013:
Currently when car warms up during idling what is your rpm value. Could you emphasize further on how battery removal was done that was used to start another car

Kashif:


Tell your mechanic to take your engine idle speed back to original setting (however he did it). The higher than normal engine idle speed is causing issues.

After you used your battery to jumpstart​ another car, your car lost volatile memory where stuffs like engine control mapping is stored. All that was needed was to drive the car for some time to relearn.

Na you cause your wahala.

Dokidoki:

na good Samaritan I Dy try do land me for dis wahala.

GAZZUZZ:


your mechanic increased the RPM of your car via the TPS. Return TPS value a minimum of 7percent.

Dokidoki:
initially when d issue started ,I raised my suspicion to the Mech dt it was d high RPM bt he dismissed it saying "high rpm go make d car dy run faster nd jump forward at startup nt cos slips"

GAZZUZZ:
the 2003 camry V6. Toyota was experimenting with electronic throttle body.

It's an interesting setup, electronic throttle body plus independent TPS on the other end.

Current TPS value will be over 20per, but the idle will still come down to 750-850 after temp values hit 80-96deg celcius, but on initial cold startup, RPM will be about 2000rpm.

Current TPS readings give wrong instructions to transmission ecu.

Dokidoki:

cn u give me a simple guide to what to instruct my Mech to do towards restoring tps value to factory settings

mayor2013:


Forget about this your mecho doesn't have the equipment. Or you want more damage done to the existing

Dokidoki:

am nt in Lagos
I wnt be returning to d same Mech
but I need to know what to tell a new Mech to do...Nd also to know if he is doing the right thing.
i will be going to a more standard autoshop

Dokidoki:
fixed throttle position sensor issue.gear issues persist.
scanned vehicle..... transmission oil pump failure and transmission oil temperature sensor failure.(wrote codes down bt cnt find d paper).
Mech advises transmission change.
another Mech says since it's ten pin gear,it cn be repaired.
personally no moni for trans change yet.
advise pls.
cn it be repaired?or do I jst save up for new Trans.
any other suggestions are welcome.
