I have a '94 wagon w/5spd. Ever since weather got cold my reverse grinds when engaging almost everytime (clutch in all the way). Is it a linkage problem?

    Depending on the milage you might want to change the tranny oil and use synthetic. Cold weather has that effect on most manual trannies. Even my very loose Wrangler like it if I select any other gear before I put it into reverse.

    I'll take a guess that the clutch is not disengaging completely. Maybe the slave cylinder, which (unfortunately) is internal in the Volvo, I think. This is how one of my Saabs and my Porsche's failed. Never the actual clutch disk.

    How old is your clutch?

      It may be that the clutch is not completely disengaging, but not necessarily so.

      This grinding that you describe is not an uncommon occurance with all manual transmissions. The high viscosity of the transmission oil, during very cold weather, causes some of the components in the transmission to start spinning due to the churning of the oil from the other components. If you go directly in to reverse while these components are free-wheeling, you get grinding.

      Do you place the transmission in first gear before shifting it in to reverse? It is something that you should ALWAYS be doing, warm, or cold, weather. Depress the clutch, put the shifter in to first gear, then move the shifter in to reverse. Putting it in to first stops the free-wheeling of any of the components.

      If this procedure solves your problem, then the problem is likely not about the clutch not disengaging. If you still have a problem, you likely have some issue with the clutch not disengaging.

      BTW, the clutch slave cylinder is NOT internal. It is right out in the front of the drivetrain.
