Crazy K Posted November 25, 2005 Report Posted November 25, 2005 My Question is to ask if anyone knows how to determine what ratios a 4t60 or 4t60e tranmission has, if they are indicated on the tranmission plate or spid? The reason i ask is that my: 91 Lumina Euro ran 2000 rpm at 60 mph (god rest it's hulk) 92 Lumina Sedan runs 2000 rpm at 72 mph(w Euro cluster) 94 CS S runs 2000 rpm at 72mph 4t60e 95 CS SL runs 2000 at 60 mph. 4t60e And needing a transmission for a 91 CS... I'd like to get the higher drive ratio 4t60 tranny from a junk car, (with no way to test drive):? I want the more efficient one, but also have no way to determine the deceased tranny's ratio Quote
skalor Posted November 25, 2005 Report Posted November 25, 2005 Why don't you just look at the RPO codes to decipher what was in the car. http://www.rpocodes.com Quote

If i go to the boneyard and they have loose tranies....... does anyone know if the metal tag on the trannywould tell you on it too? -ken Sadly most of my spid are absent, time to contact gm for those Quote
fastbird232 Posted November 25, 2005 Report Posted November 25, 2005 Don't bother contacting GM about your SPID, just go to your local dealer and they'll print you off a detailed sheet for free. Quote
BIGBULS Posted November 25, 2005 Report Posted November 25, 2005 I'll bet plenty of cash that all 4 of your cars have a 3.33 axle ratio (what all 4T60/60-E LHO's and L82's got)..................... The rpm differences are probably due to differences in the state of TC lockup. Quote
