RaceME Ultra Transmission Shifting Hard?

[cklein728]

I just installed the RaceME Ultra tuner, and everything is great other than the transmission is shifting hard in and out of the 1st and 2nd.

Will the WARP fix this issue?

I only deleted the truck to get rid of the EGR and DEF.

I do not want the extra HP and performance (although it's nice).

I've emailed RaceME and haven't gotten a response.

I'm reading this is familiar with RaceME.

Thanks!

Trans tuning will cause a transmission to shift firmer and particularly so on the 1-2 shift.

Having said that, though, WARP tuning is superior to the RaceME box tuning.

Thanks, Ray!

My 2021 possibly has the CP4 fuel pump but not positive.

What's the best way to find out?

RAM went back to CP3 during the production of my truck, LOL.

Never saw a 21 with a CP4.

The easiest way to find out is to take a picture of it and post it for us to look at here.

You will want to go with the WARP tuning from DRD.

I ran the RaceME box tunes for about 6 months, and my transmission was shifting alright, but not as it should have.

I finally bit the bullet and got ahold of the WARP tuning.

They make tunes specifically for your exact truck and setup.

It's great.

Ever since I did that, I haven't had any issues.

Shifts like usual now.

I don't notice any power gains or anything, just smoother.

I also didn't want/need the extra power, so I left it on the first power setting.

Works perfectly.
