Hi everyone. Just wondering I have a mk1 mx5 eunos Japanese import and it’s a automatic which I believe is rare. The gearbox seems very sluggish when pulling away is that normal as it’s a old style gearbox compared to a new modern one ???

I wouldn't have thought the autobox was rare but they're usually in good condition as commonly kept as second cars so garaged & lower millage (km-age?) than manual

also, the autobox might benefit from a service (fresh oil & cleaned filter) and theres a vacuum module on it that can fail - worth investigating?

also, the autobox is supposedly strong...

as to sluggish, the 1.6L auto engines were detuned to ~90hp whereas all Eunos 1.6L manual & the earlier UK engines (pre 1.8L engine release in UK models) were 115hp..
a good engine service & making sure the old exhaust is not blocked can also release a few hp

Rich.

Brilliant mate. When you say filter in the gearbox what do you mean by that ???

transmission oil filter, more of a strainer than filter but can be blocked with ~30 years of gack

It’s a bit of a pain to change the tranny oil on these so be prepared and have a read of some guides.

I have the auto and changed the gearbox oil. You need to drop the sump from underneath the car as there is no drain plug ( or vacuum the oil out ). A messy job, but once changed, the gearbox performs much better - faster changes and a lot smoother.

I’ve heard the filter is a pain to change, is that the case?
