Switching between spartan tunes

[gregw338]

When I switch between Spartan tunes do I need to do a transmission relearn every time I go from 210 tow to 275 or even the 250?

It is always good to do some kind of trans relearn for the big tunes. Maybe not so much the 250 as the 275 tune and higher though. It makes the shifts much more consistent if you do the relearn.

Kinda expanding on the OP's question. Let's say I run the 210 as a daily driver. I switch to the 210 tow for a weekend to tow a camper. Do I need to do the relearn for the switch to the 210 tow? How about back to the 210?

Same type question if I run the 250 as a daily driver. Do I need to do the relearn to go to the 210 tow for the weekend? How about going back to the 250?

I would like to minimize the relearn runs. I know you guys say it's OK to run up to 75 mph in 4wd hi, but that whine still makes me nervous.

I would run the 210 TP and the 250 tune through the gears a few times after you load them up. The 210 tune isn't going to need a relearn as bad as the tunes that have harder shifting.
