way confused about the oil required in a 1998 GTV V6 5 Speed gearbox.
Owners manual says Tutela ZC 75 Synth GL4 (Manual specific for 5 speed)
Workshop manual says Tutela ZC 75 Synth 75W90 GL5 (Manual covers 5 and 6 spd)
Workshop manual is circa 2003.
Found the Tutela ZC 75 details file on line, it say 75W80 GL5. Presume this is current, and rings true with comments on this forum. At some stage the formulation of ZC Synth must have changed.
If anyone has experience with a GTV V6 with 5 speed box and Q2 diff, would be interested to hear it. At present I'm thinking Redline MT90 75W90 GL4, which at least matches the owners manual, and the oil weight in the workshop manual.
