trans interchange olds 88

can you tell me why a trans from a92 will not work in a93
the interchange book shows 93 all by its self:screwy:

The 92 has a cable and the 93 is electronic.That is one diffferance.The other differances are the gear ratio,color of the plug in and the wiring for the valve body.To find out the gear ratio,there is a metal tag on the case somewhere with two letters such sa pw,ws,etc.The third letter in the rest of the letter and number in a list of letter with the letters I mentioned.
