I have a2010 Buick lecerne 3.9 l with the 4t65e tranny I'm about to put a 2007 4t65e tranny from a Buick lercene I know the final dive ratio on them are different. 2010 2.93: ratio and the 2007 2.86: ratio. Does anyone k kw how hard it shift with the 07 tranny in my 2010 and what can I do to it to smooth the shifting once I put it in there

That'* such a negligible difference that you'll wonder if you ever swapped transmissions.

Ok thank for the information

How do I decipher the tag that iis on the side of transmission and by the stamp that is on the casing that * all I have I bought the transmission from the junkyard what do the letters and numbers meen on the tag
