That's exactly what I'm hoping. I have yet to locate the ID tag on my transaxle but since It's N/A there's I'm putting my money on the 3.05 gearset. The diff has been confirmed to have the 3.05 ratio, and if you do the math, using any other gear chain set except the 35/35 tooth results in really funky ratios that are not at all common in anything except maybe a minivan or suv with the 4t65e
This was taken from RegalGS.org.
With 2.86 diff:
Use 35/35 gears to end up with 2.86:1 (my LeSabre is like this)
Use 37/33 gears to end up with 2.55:1 gears
Use 33/37 gears to end up with 3.21:1 gears
With 3.05 diff:
Use 35/35 to end up with 3.05:1
Use 37/33 to end up with 2.72:1
Use 33/37 to end up with 3.42:1 (did this for my Regal)
With 3.29 diff, as we all know:
35/35 gears give 3.29:1 ratio
37/33 gears give 2.93:1
33/37 gears give 3.69:1
And the Series IIIs were the first SULEV compliant vehicles. Most likely 3.05s. In regards to the Tranny going out not possible with the the shape it was in a month ago when I changed the fluid and filter. Not even a full shade darker than the fresh AC Delco DEX VI I put into it. I dropped the pan once at 42k miles and there was tons of metallic sludge from steel and friction disk material which had settled in the pan.
Last month I dropped it at 119k, and despite beating the piss outta the car on a regular basis there was no metallic sludge PERIOD! A fine silt in a few spots on the pan, the top of the filter had a thin film of material and that was it. As stated fluid was in like new condition.
