01 TRX500FA1 throws codes 11 and 5 and wont engage ANY gear ---- (N) sounds fine ----- any other gear sounds as if it is trying to engage (grinds) machine will not move in either direction ----- shift motor is fine ----angle sensor tests good but slightly erratic----- I found a post refering to pg 23-15 ( presumably in the factory service manual) that talks about swash plate unlocking procedure but it sure aint in my clymer manual ! ------ any info would be GREATLY appreciated---- Thanks , Psychosteve

Pull the plugs on the angle sensor and ecm Clean the contacts inside and dielectric grease them before reassembly.

Hey Saber------- pulled , cleaned and dielectric greased the ECM and angle sensor plugs ---also , I cleared the codes and tried it , no change in function , but now throws a code 10 that my book IDs as a hard ECM failure , codes 11 and 5 did not return , ( did I mention it takes a couple `o seconds to start grinding gears after going from Neut. to any driving gear , like delayed engagement in a car trans ? )------also , the failure happend after stopping on a rather steep hill to pick up my glasses and when i proceeded down the hill coasting in 1st gear ( low range)it ``clicked`` all the way to the bottom , about 50 feet , and hasent engaged a gear since .--- any Ideas ? ------ Thanks for your time & help , PsychoSteve

Code #10 is ECM (fail safe relay) .. Which has nothing to do with the bike moving when shifted from "N" to "L or D" .. There are several things that can/will cause the bike not to shift BUT it should still should move and drive ..
If the ECM picks up the angle sensor didn't move the ECM will put the bike in fail safe mode (2nd gear) , this is for the driver to slowly drive home , to re-set it you have to cycle the key off/on ... Now that you said there was a clicking Im thinking the oil pump drive chain came off in that case you need to dtop running the engine AS IT HAS NOOIL PRESSURE!! and bring it to a dealer to have a pressure test done

The trouble could be in the sub-transmission but if it didn't have the oil pressure test done then myself I wouldn't run the engine..

This aint good ------

Hey saber -----I did the oil pressure test and as you ( and I ) feared , the thing shows an un-steady 5 psi or less . I tried to read all the pages you sent but I cant get my computer to enlarge `em enough to read ! ----- as before , I`m at a loss as to whats next----- HELP ( PLEASE ? ) -----Thanks for your time , psychosteve. also , my useless clymer book sez to inspect the check valve and spring but doesnt tell where it is !

Low oil pressure could be the transmission, oil pump or relief valve. My guess is the check valve. You need to inspect that and replace as needed.Check valve is 13 and 14..
Let me know what you find.

Still no luck ( God loves elk and / or hates me ! )

I checked the valve in the oil filter bolt ( again ) it has no wear marks/galling in the bore or the valve itself and moves quite freely ---- re-assm. it and still has no oil pressure ---- the page you sent me this time is the one I saw in one of your previous posts that refers to the swash plate unlocking procedure on pg. 23-15 --- do you have that info ? ------ codes 11 and 5 have not returned but code 10 is now constant ------- my clymer book shows there is another check valve ( pg 54 pic. 24) somewhere but does not specify where it is and I cant seem to find it ( somehow I just know I`m gonna feel stupid when ya tell me ! ) also , the ``ratcheting `` noise they speak of is exactly what it sounds like.Anyway , I cant thank you enough for all your help , Psychosteve.

Whats up Saber ------- are ya tired of me already ? ( I wouldnt blame ya !) but I sure do need your help , takin` this P.O.S to the dealer is out of the question due to the $$$$ . I`ll be lucky to afford the parts much less the labor. ---- Let me know whats up.---- Thanks , Steve.

The oil pressure should be around 22 psi at 1400 rpm and 116 psi at 5000 rpm.Code 10 Puts the ecm in failsafe but that just limits the machine to 1st and 2nd gear AKA slow riding to get you home but if the machine is not producing oil pressure its a no go.I have been looking for that second check location and cant seem to find it yet. The next route I would take is verify that the oil pump chain is still intact.Im going to keep hunting for the check location I will keep you updated..

I`m gettin` on checking the pump chain and will let ya know this AM what I find ----Wish me luck !----. --------- UPDATE , I`m in my clymer book (again) and as near as I can tell from it , the engine has to come out and the cases split to access the pump chain ------ PLEASE tell me it aint so ! --- ( if so I am capable and equipped to do so but am hoping you know somthing clymer doesnt ) AGAIN . Thanks Saber , awaiting your advice . , Psycho.

Hows it goin? I've been following this tread,,,hopping you find the fix! I've got the same issue. Even in neutral the engine doesn't rev freely, but it rolls no problem. In neutral or any gear it just bogs down. I'm getting A code 5 and 10. I've replaced the angle sensor and down all necessary cleaning to connections with electric grease. Now I'm just waiting to see if you find the fix!

The same thing happenned to me, I was drivin up a small hill, when the tranny felt like it gave out, now theres no gears forward or reverse, and all it does is grind when u put it into forward or reverse. Has any one figured this problem out?
