My Honda CRV-2000 manual transmission does not

Over drive lamp fails. I guess or is it flashing for errors.
the service manual covers all that , buy it and read ?
problems with 4R70e transmission , not told. clearly
scanning the PCM now is what is best done.
any time a transmission like this fails to shift the PCM tells you why or how it was detected. via what. with DTC codes
why not scan it.?

OD function. real name is 4th gear is overdriven
so if the tranny stops at 3rd gear we say 4th gear is dead.
4th gear is 0.70: 1 ratio.
engine spins 3/4 turn(near) and drive shift goes 1 full turn
as in overdriven gear.
now lets talk dead 4th gear, all the ways it can happen
sadly lots. for sure you not scanning the PCM first to see why.
speed sensors lie
transmission sensor shows overheating,
engine load is too high. 4th gear makes that worse so why wreck clutch packs doing that and it sure does not.
learn the transmissions are shifted by speed and loads.
load on the engine if tops.
VSS errors, OSS errors
and more, even a weak engine, is a cause.
sorry but this is how it all works
and you can not fix modern cars and trucks lacking a good scan tool..

it is inside the transmission THERE ARE 5
4WD SHIFT ON THE FLY.
THEY ARE PART OF TRANNY VALVE BODY,VB
SO THE QUESTION REALLY IS HOW TO REACH VB (DEEP INSIDE)
just read the manual
OR ASK HONDA , AMAZING NO, THEY SELL PART

MAZDA yes.
fuses all good
and forgot to scan the PCM first.
you need to scan it.
flare is mostly caused by bad transmission
the E box, electronically shifted by solenoids
just one bad solenoid wire can make shift worn
or a wire top any of he speed sensor, intermittent can confuse the TCM.
Id never ever do what you did.
Id drive it and scan it at the same time, my scan tool does logs
or if no log option, 2 person job, one drives other scans.
electronics can good ,bad or wildly intermittent. learn that and it becomes obvious what must be done.
p0733 which means that my third gear ratio is messed up.?
if you buy he wrong used or rebuilt transmission and the new box has wrong gear ratios,.as many do or gee most.
then THE TCM will be angry and not know what to do.
that TCM only works on one specific box and tranny parts codes.

also some cars this year Mazda. uses ABS as speed sensors
and if fails that the transmission will not shift correctly

learn to use a scan tool and do so as it fails and use the scan tool pending button and pay attention this time.

I replaced the RR wheel speed sensor yesterday and the car shifted just fine.

my Jeep does the same thing 2008 manual transmission
the speedo , has no , rear 4wd speed sensor at all as they did back to the first cars made. 1929 to 2000 year.?
when ABS was put in, the 2 engineers talked for the first time? LOL

and 2nd said why not use ABS for speed, (tricky in turns but works)
see?

as you can see cars are more complex now, lots.

learn that most transmissions seen may have many gear ratios
that must not be mixed up , real seller demand VIN and end serial.
if this was done wrong ask mazda if the PCM TCM can be reprogrammed to the wrong ratio box. I bet answer is NO.

USA spec car in USA? not told
2.3L inline 4 banger.DOHC +VVT cam. 5sp, M/T
nor real name of the box told.
Vtec is honda name for VVT, valve variable timing, and is not a transmission part at all so is off topic if we want to do 1 at a time.
a wise idea that, leaks are your problem.as all are.
your post seem clueless, here, find a real shop and get it fixed?
vtech bad causes huge engine power loss, for sure stuck in idle mode. so lets end that here.
and talk the box, what box 5 speed is it
not told at all
honda says 5speed is a manual transmission M/T
the silly cable to it is bad.
end story, endless.
2 cables clutch release snapped i gear. makes it hard to shift if you do not move car bay hand to N./ (a trick to lean 2 man job) as all tow truck drivers know for 100 years.
shift cable bad. (or levers to it)
see this first photo , one can drop off links to that #8 part and shift the box by hand, sure can and if can the box end is good .
box means transmission box in whole.,, mech jargon.
all this is pure mechanics 101 problem shifting any M/T is.
photo 2 is lever #2 id and cable set 6
one if bad, looking only finds it as is 100% pure mechanical parts.
end to end. no brains no CPU or TCM brains here, just real gears and levers and flex steel cables that love to fail not lubed regular.

Sounds like the transmission fluid temperature is high. Check for blockages of the fins on the oil cooler if there is an external one. The oil cooler inside the radiator won't cool properly if the coolant level is low or the radiator fans are not running at full speed.

The transmission shifting is controlled by computer, so if the gearbox has been replaced the problem with the shifting lies in the wiring or the Transmission control module, what that issue is will require special testing and likely a wiring harness pin out breakout box special tool. I would suggest you seek professional help on this, but that is entirely up to you.

The transmission needs a rebuild.

Does that transmission have external shift linkage? Sounds like a linkage broke or the neutral gate is way off.

Does the high-pitch whine exist when the engine is just running? Not moving (transmission is not in gear)? Running but with transmission in neutral (coasting down hill)?

Has the Transmission fluid been changed every 30,000 with Honda ATF-Z1?

If some one has put in GM Dexron III in it instead, the transmission may not shift properly and it can damage the transmission over time.

Also if some Express/Quick Lub place has flushed your Honda Transmission Dexron III or any type of Flushing agents, it's probally going to have to be replaced. Google "flushing Honda transmission" or MSN under "Express lub Transmission flush Fraud". Those back flow flushers systems damage the internal valves of many modern transmissions, both import and domestic and have NEVER been recommended.

Suggest taking it by a Honda Dealership or a aftermarket Honda/Acura ASE Certified Shop.
