Second Gear Starts
Anyone out there with an fmvb 48re that starts in second then grabs third? Just trying to figure out if it would be to hard on the bands/clutches...

Tyler, you’ll be fine. I start in 2nd and it’s held just fine. My transmission builder said it was fine also. I’ve found it actually helps the truck not pull through the brakes as easily while getting the turbo up to boost as well.

People do it, but it is harder on the transmission.

Perfect, that's what I was wondering about, spool up isn't the problem with the 3k stall. With 5 hooks left I just didn't want to end up smoking the bands/clutches in second. Think ill give it try in Madera this Friday!

I thought 2nd gear starts is what takes out the sprag clutch, causing major damage.

I was under the impression that the main (only?) time the sprag is used is in 1st gear when not manually selected.

If you put a switch on OD you can leave in first with the OD unit engaged, iirc this gives you a gear ratio just lower than 2nd gear, when you manually grab 2nd with OD still on you're essentially 1:1

I start in 2nd with my 47re and 3k stall. About 15 hooks on it now with no issues yet. I have way less power then most of you though.

If you start in second, when are you all locking the converter?

Ended up starting in third gear this past Friday, it ended up working out better than i expected. Carried 4,300 - 4,500 rpms down the entire track. Left the line at about 3K rpms, Locked the converter about 50ft off the line. I think I could of left the line with a few more rpms. Thank you all for the advise

Nope. Starting in first gear which the selector in drive is hard on the sprague. If you’re in manual 1st then the rear band applies to take load off the sprague.
