Question about 2006 Triumph Tr 7

2 Answers

On my 1976 Triumph TR6 when shifting I get a little grinding as it goes into gear 2nd,3rd mainly. I just rebuilt the gearbox and installed a new clutch about 700 miles ago. When its cold 2nd gear is worst, then when its warmed up 2nd rear works and 3rd gear seems to grind, unless I shift slowly. Is this just tight syncros that were replaced in the rebuild. On the first few shifts of the day when I depress the clutch in all the way it doesn't go into gear until I start letting the clutch back out. Its like the syncro is lined up just slightly wrong and then when I start letting the clutch back out it lets it align and slip in. any ideas? Thanks Tim

    did you replace the 3 springs that push the balls in the synchro hubs? they weaken and give you weak synchro, how does reverse work? if you have any clutch drag at all reverse will grate.

Have you checked the end float on the cranK, try pulling and pushing the pulley on the crank, those engines were famous for wearing the thrust washers and then they drop out they take the "push" from the clutch release mechanism and if the play is too big it causes drag.

Sounds like a sychro problem when you rebuilt. I have always found with my gearbox, even when warm it is easy to beat the sychros so i make slower changes. Unless you fix the sychro rings the problem will only get worse

Metal grinding noise from gearbox


Pull the gear box drain plug and check for heavy metal stuck to the magnet. I suspect that the clutch in-put shaft bearing has failed. If so you will have to have the gear box rebuilt as the metal will have affected the other bearings

I was driving to work this morning and was in 3rd gear, went to down shift at a stop sign and its stuck in 3rd gear. 1988 jeep wrangler. It has been grinding the gear for a few weeks now everytime I change...


The 3rd Gear Synchro is worn or damaged, which is why it grinds when you try to upshift or downshift into 3rd gear. When it goes out completely you will have a very hard time shifting into 3rd gear, since the Synchro lines up the gears to make shifts smooth and easy.

My ford F150 won't shift from 2nd to 3rd. Does anyone know what could be the issue?


Usually the transmission needs to be rebuilt in that situation. It's a very common problem if that's the famous automatic overdrive transmsission. AOD I have had three trucks that have done that. It usually starts by shuttering when it shifts and than finally goes out. Sometimes the Lucas transmission treatment gives you a little more time, but it sounds too late for yours. From what I understand (mechanic told me) that when the overdrive goes out, it takes third gear with it. If you drive in hilly areas, that overdrive is shifting in and out all the time as you go up and down hills and wears it out. My Dad had that hapen on his F150 and he replaced his transmission with a junk yard transmission that turned out to have the same problem. I had that transmission replaced with a Jasper rebuilt and it worked great. I think it was $1300 for the rebuilt trans with the old one core trade in. I think when 3rd gear goes out, you can only go about 45mph without over reving the engine. I saw that same problem with a Ford Crown vic with that same transmission and 302 engine that my neighbor had.
Did your third gear just go out all of a sudden or were you getting like a shuttering or kind of a grinding sound when it shifted?

Hi i have a 1976 mk4 1500 spitfire 4 speed box i have rebuilt the gearbox and replaced the syncros because the split ring had broken and the syncros were damaged when the box is cold i do not have any...


3 things come to mind, firstly the end float of the 2 ball races, one in the first motion shaft (the one the clutch sits on) and the main shaft, top gear locks these 2 shafts together, 3rd uses the layshaft, too much play stops the synchro working, secondly check the clearance between the bronze cone and the teeth on the hub, there needs to be clearance there (if it is close when cold heat will expand the bronze more than the steel so no clearance and the taper no longet binds the 2 together) lastly get new springs (3) under the ball bearing detents, this is what pushes the bronze ring on to the taper on the hub, if they are weak the synchro will be.

Grinding sound


What is happening to you is worn out sincronizers in you transmission. They are used to mesh the gears between shifts. They are made of brass and wear out easily on the 2nd gen cars. It grinds normally going into 2nd gear and into 3rd if its really worn. If you want a stronger transmission buy the 93 and up 3rd gen tranny. It is an upgraded transmission with dual sincros. Yours does need rebuilt. Or you can find one on the MR2 board for a good price used. I prchased a 93 trans for $1000. An older one will be about 200. Also it depends if its turbo, lsd or not. Good luck!

1972 Triumph Spitfire, 3rd gear grinding


Jumping out of third was a common problem with the Spitfire quick changing up from forth gear would beat the syncro and chip the teeth on the drive dog then the bits would stop the syncro from engaging fully and it would jump out. If you replaced the syncro and the drive hub it may just be a bit stiff, the selector also wore quite quickly and misaligned the drive hub causing it to be hard to select.
I will scratch about in my very old manuals and see if I can find the spitfire gearbox manual, If I can I will post it.
