Lost speed.5th gear stoped working - 1987 Honda Prelude

Trans internal failure.

This indicates a problem in the transmission control module as it is not activating the solenoids/servos and consequently the sensors that read turbine speed and output shaft speed are not reading the correct difference of the two units . Have this checked out at an accredited auto transmission shop.

because of the close gear ratios and the synchronisation action ,it is possible to change gears without the clutch if the engine rpm's and road speed are close matched. If you put it in 5th gear and the engine rpm's increase without an increase in road speed (gear does not engage) then it is possible that the gear on the out put shaft is stripped. This is a common problem in vehicles where 5th gear is engaged and the vehicle load and speed is excessive inducing excessive wear on the teeth of the gear causing them to fail

what I can tell you is that there have been a bunch of problems reported on your 5th gear troubles...solution: take it to a garage.


Thanks, Terry

can be lots of things,,, 4wd or 2wd, must i guess that?

let me guess, easy, and cheap first. ok? no need to go hog wild on guessing, at your expense ,no?>

1. all vitara/tracker/sidekicks, all have the 2 plastic fittings in the shift box, go, well, to dust, or crack, and then the shift lever bounces and goes out of gear or in fact was never fully in 5th gear, detents.



2. loose bottom rear transmission mount, (beat to death)



3. shift rails failing, (detent failure (springs and balls)



4. burned up fork on 5th gear, due to running trans dry. or near or GL4 fluild looks like, tar and metal filings ; ever consider do ing the service on that, drain and fill, running it on 24year old gear lube?



5. the 2 front rubber plugs love to fall out (glued in) and then GL4 slowly is lost and gears/bearings and forks are wrecked.



6. bad 5th gear bearing, rear.



7. bad 5th gear front bearing. if flops about, and jumps out of gear.



8. 5th gear synchro ring, broken, causing ill fitting 5th gear DOGS

bearing 30 and 31 are the 2 bearings mention above.

the last guy with 5th failing gear 35 , spins were wrecked.

running trans near dry,. expensive fix. with new cluster 26



see plastic 27 below.

that page even shows how to run and shift trans with extension housing off, to prove the box is good or bad, such a deal , no ?

what gear? if its the 5th in the nv4500 there is only one fix, none of the others work! there is a new shaft from quad 4x4 that is a after market gear assembly that will be the last time ever 5th gear comes off guaranteed . about $2800 up to do

not unless fifth seases to the baring's. but then it won't even go in to 4th or 5th. it's probably your sincro's that r bad between 4th and 5th.

You may need to adjust the shift linkage. As far as the roof check the fuse; if the fuse is good; it could be the switch or the convertible motor.

Sounds like you may have bent a shift fork or your cluster gear has some missing teeth on it now. I would venture to say that is it a bent shift fork. This will require the transmission be removed to gain access to inspect and repair.

hi mandy

if it only revs when you put it in 5th gear then it is not in fifth gear. it may look like it but it is not. try moving the gear selector from fourth into neutral releasing the clutch fully then applying the clutch and initiating fifth gear. if that does not work try placing it into one of the other gears first without releasing the clutch and then selecting fifth.
you should be fine driving in four gears as long as you dont travel on the audobahn or at speeds like your on the audobahn. Just watch your redline. try not to go past it. i think it is actually better for your car to drive at higher revolutions than lower as it cleans out your combustion chamber of carbon. on the other hand it is ******* your engine to drive in the red line constantly.
but 3000 rpm in 4th gear probably has you driving 130km/hr (82mph) which should be sufficient and your redline probably does not start until somewhere between 4-5k
