transmission questions

[danyvaly]

I have a 1994 2wd tranny. it has 130 k.

The mechanic says it needs two quarts of oil. he checked the oil and said oil is fine and is not smelling burn.

I run the tranny for 1500 miles like this. Did the tranny suffer? The tranny runs smooth it has never been rebuild.

another question:

when is going to shift to second it does it at at 3000 rpm instead of of 2000 rpm. can this be fixxed without a rebuild?

q3

what oil do you recommend? also the mechanic told me to use an additive is this wise?

thank you
