Re: 5R110 Transmission
There were different gear ratios in the 5R110 over the years. 2003 & 2004 had the same ratios. 2005 had a change, and another change happened in 2008.
The ratio changes were so slight that I'm almost certain there will be no problems. For example first gear changed from 3.09:1 to 3.11:1. That's 2/3 of one percent. The OBDII can't pick up a change that small. The 2007 should have the 3.11 first gear.
