My new project honda cr v 1998

Am not a novice when it comes to car but my main speciality is electronics but this is one is starting to give me headace after making the car ready for the road, from nowhere auto transmission is playing up

it has developed a problem with automatic transmission,when you start the from cold it would drive fine and changing but the moment the temperature reaches normal operatives levels that when it loses the drive the car has 140000 miles on the dash

it started when a friend slammed on the accelelator when testing the brakes after bleeding the brakes. After 15 mins of driving around the car lost drive, in D the car would behave as if it is in neutral at one point the revs and speedo would record a reading revs at 2500 speedo 20mph but the car would not move , tried all gears still nothing. Changed fluid still the same problem nothing is flashing on the dashboard



i want ideas before i open the transmission (a friends specialise in auto gearbox)tomorrow am adding transmission stop to see what happen

ZIM DRILL,

Unfortunately, am the wrong person to offer suggestions to auto transmission issues. I have no interest in what goes on in those boxes. For that, i know little about them. How i wished i could help.

I would adviced that you widen the search to your auto trans issue by not limiting the search to only 2 forum members. You never know who may know what truly is wrong with your transmission. Goodluck.

i have done my research and nothing is matching my problem and thats annoying me becoz when i go blind when i take off the transmission

Even though the MIL is not on, I still think you should scan. It seems to me that the car has entered fail-safe mode. The sudden thrust on the throttle probably snapped on a sensor in order to prevent damage to the engine or tranny. If it were a Nissan I would have suggested you look over the camshaft sensor. I know little of the CR V (Honda). Yet I doubt if it's a tranny issue.

Surely, a car displaying such symptoms would have a code stored in its computer. What you are experiencing is limp mode

wrong trans fluid, use the right one and make sure its up to full level

sultaan: wrong trans fluid, use the right one and make sure its up to full level

I'd be surprised. I thought Zim should know that. Again, the car started acting up after the test drive, before the change in trans fluid.

there is no code or MIL light

cam sensor does affect transmission but starting the car, of which mine starts and drive only lose gear after reaching average operating temperature

nissparts: Surely, a car displaying such symptoms would have a code stored in its computer. What you are experiencing is limp mode

limp mode allows you to drive at limited revs and a light will show on dashboard on mine only the ABS which i scanned to know which sensor to change

sultaan: wrong trans fluid, use the right one and make sure its up to full level

the problem started before even changing the ATF after changing with new and filled the right amount still the problem is there

Maybe, the car has been charmed. Just kidding!

The thing is, not all codes stored in the ECUs will lite MIL. In such situation, the univeral or generic scanner wont see such codes. It will report "no error code found" even though the codes will be though. Only a special scan tool designed and produced specifically for Honda or Acura can pull such hiddrn codes. For example, i do find intermittent and permanent fault each time i scan my Lion with PP2000 (Peugeot Planet 2000), a special scan tool for only Peugeot & Citroen. Yet, the check engine light wont be on. But when i scan with universal scanner, I will get "No error code found". I want to believe that Honda may have such scan tool. Find it and scan the car with it, you will be surprised other codes you will pull out, other than codes relating to the auto trans issue.

But i could be wrong, though. There could no auto trans error code stored. And if that is the case and if the culprit is not engine related or sensors, then am afraid, the transmission may have been saying "bye-bye" to you all these while.

mine...only lose gear after reaching average operating temperature

In the 6th gen Maxima (2004-06) world that is the classic symptom of a dysfunctional valve body. And even then it's a gradual process. I don't know whether CRVs of your model have vb issues, and if that were so the problem you describe occurred too suddenly to be the case. I still think some sensor is responsible, and if indeed you've lost a gear then your friend certainly did more than test drove the car.

i did not scan with a universal tool but with the actual procedure from honda service manual book (paper clip trick )thats the same method i used pull out the abs code so am sure that there are no stored codes i even used the honda method to erase codes then drove it till it lost gears then scan again still there was no code

i suspect a stuck valve,if clutches were worn the car would slip while shifting up or down but it does not, he drove the car while i was the passenger nothing he did that was out of the normal driving

the idea of opening it is making me feel lazy to start the job

then i have to ship it to tb joshua

If you dont have a code then this is a mechanical issue and not the transmission.
Something like the rubber connecting the airbox to the throttle body being loose.
Examine the engine bay thoroughly and look for something which may be missing or loose.
Also, you can be put in limp mode from abs issues. Is the abs/tcs/slip light still on?

what makes me feel lazy is that i have done so much on the car sorted the bushes front o/s then front drops links (MOT)then pimping it with a remote start, was looking forward to put tints at the rear windows then a window auto close module

nissparts: If you dont have a code then this is a mechanical issue and not the transmission.

Logical. Explore all the relevant possibilities, before finally deciding on the transmission.

you are missing the facts the car drives fine when oil ATF temp is low once it reaches normal operating temperature thats when i lose gears, when it loses gears and switch off let it cool down it will drive fine untill temperature raise to normal then i lose the gears

so the problem is inside the gearbox

ZIM DRILL:

...the problem is inside the gearbox

Ok pal. Let's go inside

No it's not.
What you have just described is limp mode.
It resets after you turn off the engine for a while.
Hmm, remote start. I have seen cars develop issues from installing remote starts.

nissparts:

I would have thought that was clear enough. But since Zim is himself a professional in these matters, I'm giving benefit of the doubt.

limp mode always gives a code when scanned, meaning that the ecu has detected a faulty sensor and to protect the car it get into limp mode and a code is stored

as for remote start thats my playing ground, its a problem if it gets installed by fake auto electrician

Okay then.
Let's hope it's a minor transmission fault

A major prayer Trust Zim will keep us posted.

those one played around with the key without knowing the effects to the transponder the 1st thing first with a remote start is to find the best way to permanately make the read the chip, lots of those boxes on ebay, myself i dont use those i take off reader from ignition barrel and put the key in the middle secure them and put them somewhere in the dashboard but you must have a second key cut to use this key does not need to be coded

when inserted the car will read the key that is hidden not the one in barrel after that look for your start accesories wires etc

i even install such system on manual cars and putting a safety switch not to start in gear

nissparts: Okay then.
Let's hope it's a minor transmission fault

thats not my worry but how much those small parts inside cost there are not things you get from average auto shop if it is a stuck valve thats easy you clean up the edges oil rings you put new one

Does the engine rev normal in park (P)? if no, Check ur throttle Sensor Body.

yhemster: Does the engine rev normal in park (P)? if no, Check ur throttle Sensor Body.

Everything is normal except when it gets warm during driving thats when i lose drive
Shifting up and down is fine even reverse and park

1998 CRV with high miles mean its time for a new transmission. Old fluid was dark burnt when you changed it
