Triumph TR6 - 2nd Gear Is A Grind
|Hi guys... on another beautiful fall colors run here in Ontario (Muskoka Road 13 - the Southwood Road for those who know this favourite twisty bike/roadster drive) I was reminded to ask this question:|
When downshifting from 3rd to 2nd at about 20 mph or higher I get gearbox grinding. I have to slow right down to about 15 mph (less than 1500 rpm) to shift smoothly down into 2nd. Is this normal or a bad sign? All other up or down shifting is smooth and quiet.
|No I don't have that problem.|
The bad news is - it probably is an indication a circlip has broken or something is loose in the tranny Ken.
|Hmmm... sounds like $$$$$$$$ Mike. I'll do some homework on that. I'm into Cullingford's on Tuesday for a new windshield and to pick up a turn signal switch so I'll talk to Brian. If it's tear down time it'll have to wait until 2011. A planed rechrome of the rear bumper will use the rest of the mad money for this year :( |
|I'd look around craigs list, there have been a few TR6 NON-O/D 4spds availible here for $75...may be worth it to find a donor and then take your time with yours while you still enjoy the car. Just a thought.|
I had a simialar problem in June with a gearbox
i had rebuilt that came from a 70 that i had parted out.It got real noisy in 2nd,thus i had the 74 gearbox installed ( origional to the car ) and this one has a mild grind occasionly going into/outof 3rd.
This has allowed me to enjoy the car the rest of the
summer/fall while i decide to A. rebuild the better of the two i have over the winter or B. go the Toyota
5 speed coversion.
|Sounds like your 2nd gear synchro ring has worn. Does it slip into 2nd gear without any noise above 15 mph if you double de-clutch?|

|No CJ... double c does not make a difference that I have noticed.|
How's the new windsheild and what was Brian take on the shifting problem.
|Malcolm... will know later this week. I take the car in Tuesday. Will advise.|
|In wrapping this thread up until spring 2011 Brian Cullingford (for those who know this former BL Dealer and LBC service garage in Barrie, Ontario) suggests that I may have a worn synchro or excess play in the gear hub. |
So, I'll put aside some coin, shift gently and store until then. I'm not up for getting into it on my own.
If I can find the thread where we gabbed about swapping out a windshield I'll wrap that too. I just picked the car up this morning with a fresh one.
|Malcolm... sorry, did not respond to your question. The new windshield is a treat. Crystal clarity after looking through one that was delamming. Brian did a great install... clean. He charged $138 labour which I thought was reasonable. Glass cost was $199.61 plus glazing rubber and moulding cover.|
|JT and Malcolm... re buying another gearbox: I am one of those dimwits who'll pay $$$ to keep his car and drive train a matching numbers car. I know I'll never get my money back but sometimes I spend good money after bad... it's one of my guy things. |
CJ looks like you were correct. I'll try double clutching again in the interim.
Sounds great,a new windsheid and Tire's( 10yrs.with 5000 miles )are on my list for next year.
Have a look at the Buckeye Triumph Technical pages, there is a set of articles on dismantling and overhauling the TR 250/6 gearbox. You might be tempted to do it yourself. I have rebuilt a TR7 gearbox, it was not that difficult just time consuming.
