Just replaced my tps and this is obviously a problem so what should I check to try and fix this help please

How about putting some info on what you are working on? Such as year, engine. Or is everyone suppose to guess what you have?

Elaborate ...

We'd love to help but first let's do this:


"Let’s play a game.

You pretend that you are the only one that knows what year/engine, etc that you are asking about.

We will all pretend you never asked a question until you provide at least the bare minimum of information about your vehicle".

pretty vague question.

Hey buddy, not too sure what's going on over there but sounds like your trans won't shift outa first or 2nd gear. We need to know more bro.

Take the shifter out of first.

Or maybe take your foot off the gas pedal.

I have a 1996 jeep Cherokee with the 4.0 engine automatic trans lifted 3.5 inches with 32s and a Borla straight pipe exhaust with glass packs didn't have problems untill put the o2 sensor in some time last week

did you try dissengaging the e-brake

OK, Now that we have some info to work with. Did you do any other work other then the o2 sensor. One of the first things I would start looking for is a vacuum leak. Also start looking for any wires that you may have accidentally bumped and knocked loose. At least that is where I would start. It does sound like you may have a vac leak.
Keep us posted.

On my chevy one time the auto tranny wouldn't shift because a vacuum line to it got disconnected.

Check all your lines to your tranny.

My ebrake has been gone for awhile now so I didn't think that was a problem but good idea to check the vacuum lines new to the jeeping world though only sixteen so theres a vacuum line that runs straight to the tranny? And not recently have I done any engine work other thank cleaning the throttle body did it with brake cleaner though probably a bad idea is there another. Connecter I should check it also jumps around gears from two thousand to three thousand rpm untill I let off the gas and it picks the right gear also today it stalled out twice just randomly

My e brake has been gone for awhile so I don't think that's a problem but I haven't done anything recently other than replacing the tps and cleaning the throttle body did it with brake cleaner though probably not the best idea but I'm a new jeeper and don't really know that much engine wise yet so there are vacuum lines going straight to the tranny? And is there any other sensors I should check that would make this happen my truck also skips around gears between two and three thousand Rpms until I let off the gas and let it pick the correct gear today it has also stalled out twice coming off a stop sign or at a slow speed so just so confused on what is happening but thanks for the advice I'll check all the lines tomorrow morning
