Those numbers look about right. I drove my car for a while with 1st and 2nd until I could replace the trans. I had made arrangements for another trans, so I wasn't concerned with killing the lame trans... Then I had to replace the engine too
It gave in at the end of an hour long stretch on the highway running around 65 mph...
If this is necessary, I would suggest staying off of the highway. Stop occasionally to check the oil, both the level and the condition. Know anybody that has AAA??
