Is the early Allante transmission non-electronically controlled?

[Ralphy Boy]

Hiya guys, I'm new here and soon to be proud owner of one of these great cars. I am wondering what is the difference between the '87/'88 transmission and the later ones. Is it correct that the early ones are essentially beefed up 440T4 which do not require a computer to shift while the later ones are 4T60E's which do require a computer to shift? If the early transmission failed could it be replaced with one from an '87 park ave or Lumina etc. Those cars ran non-electronic shift 440T4's. Thanks for any info!

The answer to this question is no. The Allante's have a F7 transmission which is similar to the 440T4 transmission but has an electronic valve body and some other differences including and extra 4th gear clutch, etc. Because of the electronic valve body, it requires a computer to shift.

Yes it could but your car would set codes. You might also experience some drivability issues as well.
