I have a 1989 5.0 LX convertible, with the T5OD manual transmission. I'm beginning to wonder about the clutch. There have been a few instances recently where I have felt a surge, or what may be clutch slippage. Each time, however, has been in the rain.
I had replaced a starter last winter, and seem to remember some type of visual inspection port, or something like that, where the flywheel was exposed. I am a medium level do-it-yourself'er, and don't have a ton of experience yet, so I could be remembering wrong.
I'm wondering if this sounds right to anybody, and if rain water could be getting in somewhere that could cause the symptoms I have seen.
Thoughts?
Also, is there any definitive test for clutch function?
