TVR S Gearbox Oil

[Top Gear TVR]

OK, next job

Planning replacement of gearbox oil.

Dim question; Do I have a Type N or MT75? how do I tell? and

Whichever box it is what oil do people recommend. I find the box a bit stiff into second when cold and hear that different oils are better?

any advice much appreciated again!

[Maffe]

The mt75 box have reverse down right and have a lock ring (dowt know the word), the Typ N have reverse next to first gear
Just changed all the fluids in my s3c and used Super Quaker miniral SEA 75W to the gearbox.
As recomended by one of the mechanics at my local ford dealer who´s into raceing.

I have a Type N (Or 9, Nine). It's very baulky when cold but fine once it's warmed up. So any recommendations would also be appreciated.

I have a vague memory that this box doesn't have a drain plug - am I right? Will check the manual in a bit but as with all things S some advice on how to contort one's limbs is always useful

Thats correct, no drain plug on the "N" (Or type 9) need to use a sucktion pump, there are not expensive to buy just connect to a compressor.
Then pump in the new oil

Isn't the MT75 in an S a myth?

Never went into production?

I believe that previous threads have stated that a 75w90 oil will help the cold shift quality but you should use a GL4 rather than GL5 spec to ensure that there is no adverse effect on the synchro rings. I have just bought some Comma 75w90 from Halfords today - checking my oil as well before Spa!!!

HI all,have just bought first tvr -only difficulty so far is engaging first or reverse when cold.was going to investigate clutch master/slave cylinder /clutch release arm adjustment -but is it something to do with gsarbox oil type or just one of those tvr traits?

[wizzer]

Just check out Opie Oils website will tell you everything you need to know, and they sell all their products at good discounts.

Glad to be able to help
Don´t know about the exhaust, mine was on the way to metal scrap bin when I did this :P

I was becoming concerned that my right arm was getting too tired to steer all the way to Spa from all this blXXdy jack action required for the prep-work in advance of Spa, then the cesspit failed requiring much digging, following a week on generators cos the electricity supply failed making repairs distinctly dark in nature.

Rural Norfolk clearly has some disadvantages............

Something TVR planned to do, talked about, but never actually did.

Just think how light the steering will feel after your intensive workout.

Guys at the gym looked stange at me when I was sitting on the floor with a 20kg weight using it as a steering wheel :P

Have you considered a petrol generator instead of a hand- cranked one?

Sorry, I couldn't resist that!

my wife thought generators worked on electricity????

christ it took what seemed like hours to explain the miss-failings of her wisdom (without falling on the floor with sides splitting)

So can it be done with the exhaust on?

It was easy to change the gearbox oil on my old S3, once I got underneath it. I don't recall the exhaust getting in the way particularly.

I bought one of these



to suck the old oil out - it was very handy for squirting the fresh oil in, too.

Have fun!

Ah yes, I seem to remember these being advertised in Penthouse magazine in about 1988. I always wondered what they were for.........
