I'm reposting this as it's own thread, and yes (I DID @#$@#$@# SEARCH).

My engine like, runs out of steam at 45-50 unless i gass it.

After 50 - 55 it cruises fine, maybe allabiet a little vibration, but at 50 it feels like it's got no more motor!

 

at what speeds does your tranny shift at? i think its supposed to shift into 3rd at around 30-35 mph. when do you get into 4th? is it right around when you have your problem?
have you had any service done to your transmission?

 

Not sure when it shifts, but i just had the bands adjusted and the fluid flushed. I was having a little overun and that cleared it up. I assumed it was lockup because of the serious lug the engine takes on when it drops down.

Edit: It does shift to 3rd right at 35mph

 

Anybody? I know one suggestion was that it's just an underpowered engine, but as i mentioned in that thread, it seems hard to believe dodge would let vehicles off the line with such a dead spot.

 

Depends what engine you have, but the A518's o/d is a fairly tall gear (0.69:1) and you wouldn't get a whole lot of response after it shifts into O/D unless your speed is already up, or you gas it more to either get the converter to unlock or downshift completely. I think the quote is right on in that the converter shouldn't lock up right when it shifts, it should lock up only after you've pretty much reached your cruising speed. 1025RPM is lugging these Magnum engines, they seem to prefer it north of 1500rpm when cruising, etc.

 

It's definantly lugging, i just don't know how to keep it from doing so unless i reall gas it on the HW. IT's a 360.

 

Have the Throttle Position Switch (TPS) adjusted back to spec and if necessary, adjust it out of spec to force later upshifts and earlier downshifts. The TPS is used, along with other sensors, to determine shift points.

 

How is the TPS used when it's a mechanicly shifted transmission? Should i try to replace the TPS because i know it does help control lock up?

 

did anyone suggest adjusting the TV cable? sits on the passenger side of the TB, with the throttle closed, see how much play there is, there should be little to none. if it's too tight, it'll shift funny. too loose and it'll shift even funnier. there is a white clip that gets removed and it has something like 10~12 notches that the cable can move one way or the other.

if the dead spot is not apparent in all gears, then it's most likely the tranny up shifting too soon. a TV cable adjustment should help.

Nah the TV cable is correctly adjusted.

It's exactly on. Is there anyway to adjust the lockup?
