Castrol TRANSMAX Limited Slip LL 75W-140 Fully Synthetic Hypoid Gear Oil

Castrol TRANSMAX Limited Slip LL 75W-140, formulated with Smooth Drive Technology™, is a fully synthetic hypoid gear oil formulated for use in both conventional and limited slip differentials. It has demonstrated outstanding performance in competition vehicles employing limited slip differentials. 

Approved for use in the high performance BMW-M Series and Mercedes Benz AMG limited slip differentials.

Castrol TRANSMAX with Smooth Drive Technology™ has active control molecules that automatically adjust their friction level under changing pressures and speed, delivering a smoother drive for longer and enhanced protection. That’s why, 2 out of every 3 major vehicle manufacturers choose Castrol transmission fluids as part of their factory fill.

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.
