Funky shifting

Hey everybody. I'm new here. I recently acquired a prelude (can't remember the year off hand, wanna say either 94 or 96). It's an automatic with 120k miles. Got it with the intention of it being a commuter for my wife.

I was driving it the other night and i noticed that after the engine warms up, it starts acting funny. Say I'm cruising at like 40mph on flat ground. Accelerator is being held at a certain positiion to maintain 40 mph. Then here comes an incline. So I push the gas down a little more to maintain that 40 mph, but it doesn't kick down a gear to make it up the hill, and the speed does not increase. I can push the gas all the way to the floor and it's not going any faster, not changing gears, just losing speed. So I let off the gas and push it down again. Now it changes gears and scoots right up the hill. This is constant. Even on flat ground. Cruising for a minute at a speed and I want to go faster, give it a little more gas, nothing. No gear changes, no extra speed. Let off the gas and push it in again and I achieve the desired effect.

I mentioned it to my neighbor and he's thinking torque converter. I am a novice backyard car-worker-on-er, at best.

This seemed like a good place to get any opinions before I go and pay somebody to look at it. Sorry if this is a common question that has been answered a bunch already.

Thanks for everything!

Re: Funky shifting

try changing the trans fluid first and see if that does anything

I would start by letting the car reach operating temperature and checking the fluid on a level surface, if it's a brownish color you should change it. For that mileage i would say it's pretty immature for that transmission to start slipping unless it was really neglected, 4th gens autos are pretty reliable from experience. Also worth checking the throttle cable, making sure it has some slack to it and also checking the cable that leads to the throttle body to the transmission, making sure it's nice and tight but not keeping the lever on the transmission open.

Hello,what do you mean by tightening the cable that leads from the throttle( to )the transmission?I ask because I'm experiencing similar problems with my 95 lude and some mechanics are telling me it might be a shift control solenoid or lock up solenoid or any other solenoid assement.thanks!

Re: Funky shifting

It's called the kickdown cable, it runs from the throttle body to the tranmission behind the bottom Radiator hose near the dipstick, it's just worth checking it's not keeping that lever open, I don't think it will cause much of an issue if it was cause I had it like that for a while lol. But in terms of the solenoid I have no idea how to go along with testing them, I've seen some guys thanks the solenoid off and clean them, I would change the fluid first like the other guy suggested and see if it changes anything
