OVERDRIVE STAYING IN. help/advice

[staghunt]

Hi my L reg Stag J type overdrive has recently decided to stay in even in 1st/2nd. It seems great going in and out fine for about 3 miles or so but when it is up to temperature when you flick switch to out it won't drop out and all gears are at the lower rev's and when in 2nd there is a slight vibration possibly sliping. First checked oil level pushed car backwards to check for any locking up but OK, went out on test same thing, came home drove forward into garage again pushed can backwards again to check locking up but all smooth. looked up info given on forum so ordered 2 new 'o' for soleniod, removed after modifiying spanner thickness slightly and width shape to allow spanner in and to turn as hitting caseing otherwise. Tested by blowing down end (free flow of air to both drillings on side of shaft) powered up soleniod blew down end (no flow of air). Fitted the new 'O' rings to outer part of solenoid shaft, refitted topped with oil, road tested but same as before in /out great but after few miles/warmed up won't come out even in 2nd. The only thing I can think of that I can do is to aquire a good working spare j type soleniod and try fitting that. So has anyone got a good working solenoid that I could try or any other advice/help that may help solve the problem without having to resort to Overdrive removal or putting car in for professional to repair. I am in Chigwell Row close to bottom of M11 on east london/essex border if there is any local help out there that has any ideas/part Many thanks Greg. Mob 07952382150

Cant really help but the overdrive only works in 3rd and 4th gear so testing it in second is not proving anything. With the engine switched off but the ignition on put the car into 3rd or fourth and flick the switch if it clicks the solenoid is working.

Be careful not to put it in reverse if the o/d is stuck on. It WILL wreck your overdrive unit.

inhibiter switch iffy maybe?

Hi Greg,

I had exactly the same problem as you a couple of years ago and a replacement solenoid sorted it out.

However, as has ben said, DO NOT SELECT REVERSE. Not only will you trash the overdrive but the debris could get into the gearbox and b***er that up as well.

Only on tablet at the moment so can't go into detail but the Buckeye Triumph site will tell you everything you need to know about overdrives.

Good luck.

Many thanks for taking time to reply, I do hope it is soleniod just need to find a good one as i was told by a london stag workshop that only half the new ones that are made abroad nowdays work. PS i wonder if there is a repair kit to refurb my soleniod ? Cheers Greg

It's unlikely, but possible, that there is an electrical fault (or more than one) keeping the overdrive engaged. This can be tested by removing the fuse (23-24) as a very simple check to ensure it's not an electrical problem. Remote chance I know but worth a try as it's so easy to do.

I would strongly suspect the inhibitor switch. It should prevent selection in any thing except 3 & 4.

[TR5convalescent]

Also, DO NOT push car backwards either, with OD engaged as this will trash the OD clutch unit.

[Mike Stevens]

The inhibit switch is wired in series with the gearknob switch such that both have to be 'ON' for the overdrive to work. If there was a fault with the inhibit switch such that it was 'ON' all the time, the overdrive still shouldn't work if the gearknob switch was 'OFF'.

Removing the fuse as suggested by Simon is the sure fire way to check if it is an electrical fault or not.

Cheers,
Mike.

hi took stag out to try sugested test. reversed out of drive and took on a run while it was warming up tried overdive a few times in/out worked perfect, then went for about 6 miles to fully warm up on this very hot day, tried in/out again several times in quick sucession and worked fine. then put it in overdrive and left it in for a mile or so and would not come out, stopped with engine running and removed fuse and comenced drive but overdive still in with slipping in 2nd and low revs in all gears. so not electrical but either solenoid letting by or sticking in, or overdive locking up, so could still do with a good spare solenoid if any has one to proove which of these faults I have. probably wont be taking stag to national day due to slipping in 1st/ 2nd and worry of putting it directly in reverse. Anyway thanks all for bothering to offer help, cheers Greg

It's not compulsory to use the overdrive, so why not leave it out until you have time to sort it,. Then you can go to ND.

[Andrew S]

Good suggestion Bob and maybe Greg could get some advice when he goes along or even any parts he needs

Ok you caught me out,I was giving it the big sad story to try and get someone out there to feel sorry for me that has a solenoid just collecting dust.

[Andrew S]

Greg, as you say it can't be electrical so has to be mechanical. Trying to think what it could be.
Can a solenoid stock?
Anyone?
