So now for the bad news. My bro made it up with the car and it turns out it is a 94 LeSabre with a L27, but hes not sure what kind of car the GM rebuild came out of. The RPO code in the car is a F17 2.84 ratio. My bro says that the trans could still be something else due to the smalltown backyard stuff the other guy'* at the shop do. So I need to know how to find out exactly what trans is actually in the car. What numbers do I need and where are they? Thanks.

Ok went out and looked and wouldn't you know that the tag is gone . The only other thing I see is a sticker with like a CO on it but the rest of it is ripped and gone. THere is a 772 stamped on the case by the exhaust crossover. So what makes these trannies not work if it' sthe wrong gear ratio? Is it in the tranny or the diff? can I just switch my diff into this trans? Man im kinda freaking out cause the bro just towed this thing over a thousand miles for nothing.

How noticable would it be with the ratio difference drivability wise between the 2.84 to 3.06. Does the trans shift crazy or what exactly happens? Does the computer try to do one thing and the trans do another, or is the trans on its own? I greatly appreciate your help.

if you cant find a 95 prom with the 2.84, you could have the original prom reflashed.

but you dont want to continue to drive the car with the pcm thinking it has a 3.06.
