1987/350i gear box and clutch

[tcpc]

hello,

can some one tell me if the gear box and clutch is a standed vitesse part cos i think it needs some attention, the noise does go when i push the clutch in but it does rattle a bit on idle

hope some one can help

thanks
Tony

The 'box is certainly a standard Rover bit; the clutch may be uprated if you have a need for it, but AFAIK a standard Rover one will do.
You sure the noise (whatever it is) isn't all down to the clutch, e.g. release bearing?
The Rover box uses ATF rather than 80/90 SAE gear oil and it has an internal oil pump. Using the wrong oil,or letting it drop too low can sh*g the box very quickly.

Sounds like the input shaft to me, but I would live with it unless it's really bad seeing as it's an engine out job.

There is an article about which oil to use on RPI's web site. Might be worth a look.

I would tend to use a thicker oil than ATF, I've found the semi-synthetic 75W90 stuff works a treat, the only drawback is that it's a little stiffer when stone cold.
The increased viscosity will definitly give better load handling and bearing life though.

Me, myself, and a friend are using Red Line MTL in our Wedges. Tested on track days also. Seems to work just fine. ATF oil is made for auto boxes... MTL info here: www.redlineoil.com/redlineoil/mtlti.htm

ATF may be 'made' for auto boxes; it's also used in PAS systems. I guess if Rover themselves recommended it, it should be the stuff to use. I think the point is that even the thinner gear oils must have been too thick for the 'box oil pump to provide an efficient flow; that's why they changed.
Maybe more modern oils are an improvement: I'll wait till I hear that there's a significant benefit (such as more power due to lower friction ;-) before I commit myself...

I agree with Ian - I do not want the pump to work harder by pumping higher viscosity oils and after reading the Redline site this has given me no reason to change - stick with ATF and top up regularly.

On the fluid side...Mine has been changed but not sure what went in it. Certainly rough when cold but a better feel etc when hot. As the guy only deals in Rover V8 and asscociated bits I trust his judgment. Must ask him what he put in on the last service but it wasn't ATF

ATF is also used in a lot of manual gear boxes as well.

Of Course Steve! Thought i would wake somebody...
Here are some info about the T5: www.moderndriveline.com/Technical_Bits/t5_history.htm

A Dexron-III/Mercon ATF or a DexronR III(eg. CASTROL SYNTEC FULL SYNTHETIC DEXRON®-III / MERCON®) later specification ATF oil is probably a good choise in the Rover box.

It´s because of the PUMP that the ATF oil should be used in the Rover box, right ?

[wedg1e]

Errr... is the T5 not a Ford box, as opposed to the Rover unit (380 or summat)? Or am I mixing my 4- and 5-speeds....

Sorry, I was dreaming about a Griff at the same time...

Thanks all,

how long have you been useing the redline in your gearbox for

[tvr350i]

This summer. Felt better than the earlier ATF with a hot engine on track(better gear changing). But it might still be safer using a synthetic ATF oil in the end.
