Trannsmisson differences

[Mr. Spool]

Is there any difference between an 91 240 transmission and a 96? becouse it appears that they run at differnt rpms at differnt speeds. 91 240s also run up to 120 mph with ease, were as my 96 kat has difficulties making it that fast.

any imput would be apreciated. thanks.

[Mr. Spool]

no body has any imput on this one? Thats odd....

Maybe the clutch is slipping?

91' Gear Ratios:

1st: 3.321
2nd: 1.902
3rd: 1.308
4th: 1.000
5th: 0.759
Reverse: 3.382
Final Drive: 4.083

Those are from the FSM.

[Mr. Spool]

thanks for the imput, were would I look to find the gear ratios for the 96 240 and a 94 altima, I have an online fsm but I am having trouble navigating through it.

I was told that theres a difference in the trannies since 96 is OBD-II and 91 is OBD-I. More plugs in the OBD-II iirc.

[Mr. Spool]

they rev completly different, they also get differnt gas millage out of the same engine. The only thing I can figure is that the tranies are different.

I found the specs in the MT (Manual Transmission) part at the end of the section with all the other specs. I don't see how a few more sensors could make the engine rev different though.

Are you saying it can't get to 120 or it just takes longer to get there?
