T45

[apats77]

Recently change trans oil with the factory recommended for a 98 GT T45. Shortly after the trans started to grind when moving the stick into 5th (Clutch fully pressed in). This will happen once maybe twice and normally happens the first time I select 5th per drive. Today it did it going into 2nd. I have a firewall adjuster (steeda)

Any ideas? Syncros? type of oil? Clutch adj?

Royal Purple synchomax, and just make sure the clutch is fully engaging and releasing. They recommend ATF fluid, but the t45's do a hell of alot better with synchomax, also make sure the fliud level is full (silly i know) but you'd be surprised. then again the t45's arent that strong but, if it hasnt done it prior to gear oil change, then try the royal purple.
