Using a standard boundary layer approach, the tearing mode with shear flow comparable with shear magnetic field and fluid viscosity much larger than resistivity has been studied analytically. The results show that, the growth rate in this case scales as {nu}{sup 2/3}{sub {nu}}, where {nu}{sub {nu}} is the normalized viscosity, in agreement with the numerical results of Einaudi and Rubini [Phys. Fluids B {bold 1}, 2224 (1989)]. It is found analytically that large viscosity may have a destabilizing effect on the instability. {copyright} {ital 1996 American Institute of Physics.}
