I got my 4L60E Level 5 Installed today and I had a question about the transmission settings in EFI Live. I didn't change anything yet because I don't exactly know to much about Transmission settings. My stock Transmission had pretty firm shifts but the new FLT Transmission is not as firm but I haven't gone WOT yet. I called the guys @ FLT and they told me not to increase the line pressure to make the shifts firmer because that is what kills the transmission, They told me to keep the line pressure settings at the stock settings but I don't think mine are. I was wondering if somebody with EFI Live could take a look at my Transmission settings to see if everything looks good. Let me know your e-mail and I will send you my EFI tune.

 

Congrats on the new tranny! Man, do I want 1!

 

Post up your stock tune and your current tune and I will take a look at it for you... You also need to zero out the shift times...

 

I don't know how to post my current tune, I know how to send it to your e-mail if I have your address. I don't think I have the stock tune anymore.

 

Email it to corey_lemons@sbcglobal.net

I figured out how to post the EFI file, Thanks for your help.

 

Your truck is a 5.3 right? Only reason I ask is because that is what your tune says it is... Do you have the tune before you switched to COS3?

 

Well I downloaded a 2002 5.3 stock tune, and your tranny pressures are stock... Is that what you wanted to know?

 

I was just wanting somebody to check out the Transmission settings to make sure everything looks good especially since I spent alot of $ for an FLT. I guess I always thought that firmer shifts were better but I must be wrong.

 

Did you write your tune? The only reason I ask if you did, why did you change the Optimal Timing table? That table is used for the TQ calculation for the computer, and TQ calculations are used for some of your tranny pressure calculations... Since it is lowered that might be why it is shifting soft, then again it might not... I just don't know why it would be changed...
