Title: Simple upgrades totally Changed the car
Post by: Muttwood on February 15, 2023, 05:55:26 PM
There has to be some communication between the transmission and the throttle body sensor.
The car was having a high idle and when you drove it and let off the gas it acted as if the tranny was locked up.
Now, all gone !
Also gone was the unexplained cut out of the engine, when cold.

My 35th anniversary owning this car should be more enjoyable  :smile:

Combination of low vacuum at high idle with high idle perhaps kept the converter in locked mode?

That sounds like the best answer.

The fun part is that the Pro who built this transmission, back in 1994, was scratching his head.

I was teasing him that the 30-year warranty was not up yet  :rollin:
