TH-350, how long should the shift take.

Chad Rhodes · 10-22-2009, 12:53 PM

What i mean is how long (in seconds) should the shifts take in a stocker prepped TH350. Judging by my datalogs its take .3 seconds. I am looking at the highpoint of first gear, to the lowest point immediately after the shift, same thing for the 2/3 shift. I am thinking it may be shifting slow, and thus losing some. any idea?

Does your datalog also show RPM @ shift?

yes it does. however what i am looking at is how long the trans actually takes to make the shift. I'm thinking it should be shifting quicker

Sounds more like operator error rather than a mechanical issue. I'd put your dad back in the driver's seat!

As apposed to bodily functions?

Could you post you datalogger screen shot? I'd like to look at it I have a XLT 350 that I've been working on that had some issues. It would help to see what you're looking at. Joe

.25 1-2 500 drop
.32 2-3 1208 drop

Thanks Bill, on the 1-2 I'm assuming it goes back into the converter a bit? i know I've been shifting too high on ours, going to remedy that

the red line is the RPM
