I meant it won't shift from first to second. But if we manually put on second gear, it runs up to around 45mph. Except it kind of locks.. Like it stops and moves again? As if having hiccups. It's driving us insane. And the mechanic has yet to get back to us re: the computer side of everything as he already ruled out the transmission. Said that if it were the transmission, we would have problems with the first gear and Reverse, which didn't really give us problems until we put the car manually on the 2nd gear instead of just on the regular "Drive".
 
Is it safe to reset things by removing the negative on the battery and re-attaching it again after 5 mins? Somebody suggested this.

I don't think disconnecting the battery would cause any problems unless you have a security system installed which may require some additional procedures to reset.

You can verify whether the speedometer is reporting the speed accurately by using the mileposts along a highway. For example, driving at 60 mph, it should take exactly one minute to travel one mile. A significant departure from that indicates the speedometer is inaccurate.

One mile in 68 seconds works out to almost 53 miles per hour and that does qualify as a significant discrepancy. Mitigating factors are errors in timing and constancy of your speed but I don't think they would be large enough to throw you off by 8 seconds. I agree that the speed sensor is probably faulty. An electronic problem would likely give you highly sporadic readings.

I have no idea. Perhaps someone with hands-on experience can jump in and offer some guidance. Anyone?

Sounds like a clogged Fuel Filter or fuel line, based on what you are describing.
 
I would replace the fuel filter, and then run a fuel injector cleaning additive (like the one made by BG or Lucas).
 
Should take care of the problem.
 
In the future, change your fuel filter on a regular basis. Depending on type of engine, you might be surprised to find out the interval can be as little as 12,000 miles. Fuel filters are relatively inexpensive, and most drivers who can change an air filter can change a fuel filter.
 
Take care!
