Having some transmission problems.
 

Long story short most of the people that ride my car "accidently" bump my shifter and it goes into N when driving or they "accidently" put it into 1st or 2nd while on the freeway.

The "people" I'm referring to is not me. Just some dumb people riding with me.

The transmission is an automatic. I noticed that I started getting bad gas mileage again. The shifts from 1-2 is suppose to be a little rough and the 2-3 shift is suppose to be smooth. Well now the 1-2 shift is smooth and the 2-3 shifts is a little bit rough.

The tranny oil has been changed 10k ago and it is up to level. There is nothing in the oil, in fact it looked brand new when I checked it.

The transmission is AUTO in case you missed it. Any ideas?

Might've killed it a bit.
 

Might've killed it a bit. When people joke about screwing up their auto to do an auto-manual swap (on honda-tech) they talk about neutral bombing it and such. That's basically rev it high in neutral and throw it into gear, much like what would've happened with you on the highway. Kills the transmission after a dozen or so tries (or so they say).

Nothing but problems. If the
 

Nothing but problems. If the car doesn't break down by itself then somebody breaks it.

Changing the tranny oil won't do nothing. I guess I'll just wait till the tranny breaks down completly and just get another one.

Also it's really weird but
 

Also it's really weird but my car has more power when I manually shift it. At the track my time is lower .2-.3 by manually shifting. Also If I mash on the gas on the freeway in D my 3rd gear starts at 4000rpm and accelarates very slow. If I'm manually shifting my 3rd gear starts at 4500rpm and the rpm moves a lot faster. Also in D my car shifts at 5800-5900. If I manually shift it, it does it at 6100rpm. Really weird. I don't have a Manumatic, all I have is 1,2,D,N,R,P

Re: Also it's really weird but
 

This is because your car's computer is designed to drive moderately. It shifts early to save on gas, to prevent excessive speeds, and to prolong the life of your engine.

I wish my car's computer was
 

I wish my car's computer was programmed for 2 functions. 1 is economy and the other is power.

Re: I wish my car's computer was
 

This is the exact reason I purchased two cars - one for economy and one for power.

I don't have money for 2
 

I don't have money for 2 cars. Plus I'm already paying $100 a month for insurance.

I'm guessing both of them
 

I'm guessing both of them cost him less than 2,500 to buy though (total), then more for whatev work he's done on them.

Right around $2500 for both
 

Right around $2500 for both cars, maintenance here and there costing what it would normally cost. Insurance does suck though...$155 / month for both.
