the 27 spline will not fit the 30, and the if the 30 is installed on the 27 the car will not move. If yours is a genuine 1988 you have the 30 spline.
Hope This Helps!!!

30 spline. The 27 to 30 spline change happened in late 84. Early 1984 cars have the 27 spline 700R4 trans, while the later ones were switched to 30 spline.

Unless you are good at decoding (some trans have date codes, other don't), the only true way is to pull the trans and remove the TQ conv. Then you can count the spline and be sure of it.
