like the title says... finally got my clutch to disengage(little bit of air in the system) so i started it up let her run for a bit and then took her on the road.
felt much lighter but my truck now idles at 1k rpms and i cant get her past 15mph until 3rd gear. any one else have this problem? in between gears she is so silent i can hear the tires running over the gravel on the road. then i got a few houses away getting ready to park it and she acted like she fell out of gear except the motor was idling very out of control and wasn't responding to the gas pedal(didn't die though) like Frankenstein after coming to life..lol
exhaust started filling the cab and she stopped backfiring...it was like something out of a horror film, except i had to push (over 6k lbs with the winter weight in the bed) my truck up a hill to get it back. anybody else have this problem after switching to a manual?

p.s. things i did check out before i came on here
1.ign coil, cap, rotor, plugs, wires
2.flywheel
3.clutch system
4.all the mounts (trans, engine, engine - trans bolts)

any help will be greatly appreciated.

 

95 318SLT will be best to answer this one!

 

another thing to add(i'm starting to think this problem has nothing to do with the trans swap) i checked the oil today and ,besides the need to change it, it was too full. i haven't put any in since the beginning of january and it usually leaks when it sits. so i wonder where it came from

 

I doubt it has anything to do with the transmission swap, but its impossible to say without being able to see the truck. With a 4.01:1 1st gear, my truck will still hit 35ish at the top of 1st... with the engine revved out all the way. What is your truck doing to stop it the engine from winding out each gear?

Can you be more specific about what its doing? Does the engine just cut out at a certain rpm, or does it just not feel like it has the power to pull it? I honestly don't understand the problem.

As for the idle, replace the IAC, reset the computer, and see if it clears up. My idle did some really weird things when I did the swap probably because the computer had to figure out what to do with the engine without the weight of the transmission on it.

 

with the clutch pedal pressed the motor idles at almost 2k rpms, with the trans in neutral its idle is at about 950rpms. the idle with the auto was at about 600-750rpms.(i think this is somewhat natural). but the motor shakes really bad and the backfire sounds like someone hitting metal lightly with a wrench. could it be from the motor being tilted? it seems like the motor is tilted back about an inch or two. my dad is thinking about putting a spacer on the trans mount to try and level the motor a bit. oh, and all my gauges wonder around except the speedo which seems to bounce around 15mph when driving( i actually think i was doing about 30mph in 3rd gear( not as bad as my grandpa doing 15mph in 3rd with my old daytona...lol). 90% of these issues here that my truck is pulling right now resemble what it did when my ignition coil cap and rotor went bad. like i said before though i replaced the ignition coil and cleaned the rust off the cap and tidied up the rotor.

*** i forgot to mention - i took the air filter off to see if it was backfiring out the intake and the idle seem to steady up. ***

 

this video should explain a whole lot more

I don't know what to tell you about the backfiring. The only way I can think that a problem like that could arise after doing a transmission swap is if you put in the wrong crankshaft position sensor, or a bad CPS, or the wrong flywheel.

But lets start back from square one, cause i don't remember what all you did. What engine/transmission combination was in your truck and what combination is in there now? I think I remember your truck is a 2wd? My 4x4 manual transmission was a perfect fit in place of my 4x4 auto transmission. It didn't change the angle of the engine, it fit the factory crossmemeber, etc. My 2wd nv3500 also fits the crossmember of my 2wd (was auto) truck perfectly. Since I don't have an engine for it, I can't say whether it would change the angle, but I seriously doubt it would. I really don't understand where all your fitment problems are coming from. What did you get your transmission out of?

As for the idle, like I said, the computer needs time to relearn the truck. If it still thinks the automatic is in there (which always put weight on the engine), then taking all the weight off the engine all at once when you disengage the clutch is going to confuse it. Mine acted up for a while after my swap.

 

i know its not the wrong flywheel...i found out that the 318's have a 143 tooth flywheel(confirmed it at the dealership). i'm thinking its the cps because it came of that v6 ram. im gonna go and replace it anyway i'll let you know when i get it how it works outs

 

Its got nothing to do with the number of teeth on the flywheel! Its got to do with how many CPS holes there are. If there are 8 on it, you have the right flywheel... if there are 12, you have the wrong one.

 

i started of with the automatic and the 318(unsure on the transmission model) which the automatic was only offered with the v8 that year no manual. i took the old trans out and put the new trans in(yes the flywheel is the right one, I'll go and check again to be 100% sure) the manual trans came out of a 96 ram v6(as far as i know they only put the nv3500 in them) the crossmember didn't match up because it the bolts on the auto tranny mount were front to back not side to side.(its kinda hard to explain)

besides disconnecting the battery for a bit and reconnecting it what else is there to do to reset the computer?
