Eclipse won't go past 20mph starts reving but doesn't move past 20MPH

[jayson427]

your idle has nothing to do with the tranny. i would say that is your map/tps/iac acting up. your cel code will come back on but it will depend on when the ecu picks it back up. you should still be able to get the last cel codes by checking it on the dash like i said in my other post on this thread. someone even posted a lin

also YOU need to search and read some more, not trying to be an ass either.

heres what could be wrong

input speed sensor and etax relay. your tranny could be stuck in limp mode or you could have a bad modulator valve. heres a link

My automatic 98 Mitsubishi Eclipse won't shift into 2nd gear. Reverse and 1st work fine. (Transmission Automatic Mitsubishi Eclipse Spyder Shifting)

If you read the OP you would notice my first gear doesn't work fine so that thread doesn't really apply to me imo. It won't go to 40mph, 40mph is well within first gear's reach.

I am having perhaps a different problem than that gentleman and thanks bro I can google search too and I've been doing it for the past 48 hours.

 

[jayson427]

like i said i wasnt trying to be an ass. im confused on why you would reset your battery when you had a cel code on tho. you should look up the price of a input speed sensor and see if that fixes it. you can always take it back if it doesnt work. that solenoid pack is pricey so i was trying to show you that in some cases that were similar to yours it didnt fix the issue.

I still say it's your end clutches. Remove the oil pan and visually check it

I heard another guy say that too. Does anyone have a diagram of where these are positioned on our vehicles? I'm having my mechanic stop by tomorrow and would be useful to show him.

My trans is doing the same thing but the problem doesn't consistantly do this. It shifts late sometimes. Sometimes it wont shift out of first (only a few times a week). The check engine light was on and it said tps circuit high. I replaced the tps and it still does the same problem. I've reviewed the above sugguestioins but how will I check the end clutch etc. Or is it something else?

I read on another post that it worked for a gentleman having my problem and I figured, what the heck, it's worth a shot right?

Anyways here are the CEL's codes:

Sorry to hear that you're having the same problem. Did this happen after you went turbo? I think the nitrous / turbo is too much stress on our 420a tranny's

 

[jayson427]

awesome you got some cel codes now. it took me a little while to find out what they were since 2gnt.com is not working (thats where i look up most of my pcm codes) but p0700 is internal tcu and p0732 is gear ratio error in 2nd gear.

heres the link for future reference

hope this helps man!! looks like you got some things to check out and im thinking you just need a new tcu. maybe you can find a used one real quick and just see if it works.

heres some more links if you already havn't looked it up for some tcu's.

Do I need a rebuild kit and an torque converter?

Also does the tranny rebuild take more than 7 hours and does this need to be pulled out when you do it or no

Dude go on ipt's website they have a video on how to rebuild your valve body and end clutches.

And for the last time talk to someone from IPT! if they don't answer leave a message or email them. They will have the answers to all your questions.

Alright I don't know if you work for IPT or are associated with them in any way, but dude stop mentioning IPT that's like the third time.

I called them and no one even picked up. That's not professional IMHO. I'm not going to ship my trans out there and they're not coming out here.

I don't want to re-build just some parts that are wrong, I want a full tranny rebuild bro. Do you understand that?

Which one of these rebuild kits on autozone will work?

 

[95eclispe]

Honestly, It sounds like a tranny problem to me. Could be early signs that your tranny or solenoid is starting to give out. If your not strapped for cash I would recommend just buying an OBD2 from autozone some are pricey but they come in handy. Is your CEL still on? If not have you driven the car after its off or tried another gear? Maybe try it on D2 or D3 and see if you can still get passed 20. If not most likely its your tranny starting to go out.

 

[ZacTsi]

Hey I wanted to come back and see how the tranny problems going. Yeah I remember it was such a pain but like you said DONT replace just a few parts. All I remember was the torque converter in these transmissions is crap so deffinatley replace that in your rebuild and also the transmission control module needs replaced! Its easier to have a buddy to help take the trans out and in my case has done auto trans rebuilds before. And last but not least I think My check engine light codes where just 3 different sensors or something on the transmission control module. So you probably have more then one thing wrong with the transmission or atleast in my case I did. But Good Luck with the rebuild! And whatever you do stay away from AAMCO! haha

Nevermind go buy auto zone parts. And when it doesn't work go buy another part. and waste your money. Have your transmission diagnosed by a professional and then buy the part. I'm only referring to ipt because if you need to rebuild your valve body might as well upgrade it with their shift kit.

I have an OBDII scanner that's what I used to take the pictures of the codes.

The CEL is still on.

I've tried D, L and 2 and all go up to about 20mph and then doesn't go any more. This local mechanic thinks it's the torque converter since that's when it starts kicking in he says.

 

[jayson427]

Replacing the torque converter is easy but getting the tranny in and out sucks. If you have never done it before it would take you more then 7 hours unless you have a good buddy helping. Cross member, trans mounts, starter, battery tray, shifter cables, both axles, all bell housing bolts, air intake and all the sensors along the way need to come off.

 

[95'RS-T]

OP check your input and output speed sensors for damage/unplugged. Sometimes it's stupid things like this. I had a 97 caravan that would not shift out of first gear, a reputable shop told the lady it needed a new trans, and it ended up being the speed sensor. Anyway the van now has 216k on it with the same trans.

Nice thanks for the reply noticed you're in Arizona as well. I got a buddy of mine that said it'd take him about 3 - 4 hours to do just the torque converter and that's out side in my drive way.

Does that sound about right or is he bullshitting me ?

Thanks man I got my mechanic coming over on Saturday I will mention this to him.

 

[jayson427]

if there is no issues along the way it can be done in about that much time as long as he knows his way around an eclipse. i still think there is something wrong with your tcu or it wouldnt put out the p0700 code. but your doing it right, it wont hurt to have a new convertor. if it still acts funny then you need a different tcu. if i was you i would get a head start and take all of the easy stuff of that i mentioned and let your buddy do the rest. let us know how it goes.

 

[bo0st]

My mechanic says 'it's building pressure' I might need just the torque converter (can get away with it perhaps he said) but also possibly a rebuild.

Which one of these re-build kits is for the 420a there's three of them on Autozone:

[jayson427]

All 3 kits will work for your car but it doesn't come with a convertor. If it shifted fine before your issue I wouldn't rebuild it but thats just me since the cost of labor. If you have some extra money its worth it to get an upgraded rebuild kit with a shift kit. Make sure whatever you get comes with a one year warranty on the parts.

Okay thanks. I got the converter today and I am trying to install it tomorrow. Will let you guys know how it goes.

Quit giving advise ok. He has a 420a car, not a 4g63 car. Different transmission totally. End clutches effect overdrive anyway. He is having a problem with first gear slipping and the transmission not shifting into second.

This sounds nothing like a bad converter. With a bad converter it will slip in forward or reverse. The converter is doing the same exact thing in both gears. This itself tells you that the converter isn't the problem. If you are loosing the gear after it gets the rpm up than it is likely a burnt clutch pack for first gear, a tps (controls line pressure) or just low line pressure which could be caused by a front pump that is on it's way out, really old fluid, a problem with the valve body or a clogged transmission filter. It is unlikely that it is anything electronic in the transmission. The solenoids just make the transmission shift, they don't make the trans hold a gear. The speed sensor also would not likely cause it to slip, it would make the transmission not shift, but not slip.

The fluid was very old (20K miles and manual recommends 30k change but I beat on it ) it was like black. Also I think the filter was a little clogged too.

This gentleman below had the same problem and it was his converter:

I had a dodge avenger which was a automatic tranny, and The same tranny as our cars mine did the same thing. It turned out to be the torque converter. I went threw 2 transmissions that aamco put in and they kept failing. Finally me and a buddy rebuilt a used eclipse transmission put that in and ran great. But I'll never own an automatic dsm again. haha hope this helps

So I'm hoping for the best man Wish me luck guys

Should be done tomorrow if all goes well.

 

[ZacTsi]

Don't forget about your transmission control module haha. When mine went bad I took it to autozone to get the codes and it threw 3 codes just like yours. Mine needed that replaced aswell.
