I was unable to see the fluid level in the TH400 trans in the coupe.Realized it's chrome [that HAS TO make the car faster].So I wire wheeled the chrome off the end of the stick then...I drilled two] 1/16ths holes in the stick at the add level and the full level. The fluid will fill the holes at whatever level it is, I'll try it out today;hopefully I'll be able to see it now.
