i need of some major advice, ever since i changed the motor and box the box always had this weird thing going from second to third
i tried overtaking a car tonight and it just valve danced at the end of second but i adjusted the kick down again then when i was driving it felt like it was in neutral but when you boot it, it engages a gear but its reving out but when i select 2nd on the 2 bar it drives normal :(

Check fluid level first then I would be dropping fluid and putting a service kit though it.
Possibly run a transmission flush through it before dropping fluid and service kit.
It sounds like there might be something in one of the valves the flush may dislodge it.

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

| last time i did a transmission service was on my brothers vs wagon and it was such a messy job and a pain to do if you don't have a car hoist i swore i was never going to do it again unless i took the transmission out first, if you do end up doing the service on it make shore you do up all the bolts of the transmission pan evenly or you will warp it and it wont seal |

Simple answer - as much as it needs to get to the correct position on the dip stick :)
To check the level you need the transmission warm with the car running and in neutral.
Check your level as above and top up as required. |

| One other, and this was explained to me by a transmission specialist. Sometimes the valve body on the TH700 will "stick" and when it does, 2nd to 3rd change may not happen at all. Pull over, and gently tug at the other cable connected to the throttle. One is the accelerator cable that goes to the pedal, the other is some kind of kickdown that goes to the transmission. If you pull on this cable, and you feel a slight "click" it means that the valve body is sticking. Apparently it can be fixed with a spring, but take the transmission in to be serviced. Yes, it might be a $150 gamble, but at least you'll know for sure whether the transmission is completely shot, or just needed some oil and a service |

Does it play up when you rev it when it is stationary(i.e. in the driveway) or only when out driving and under load??

| What shape are your plug leads in? If they're shot, it will cough, splutter fart and misfire if they're knackered. Of course if they're fine. another step is the boot behind thair flow meter. If it's not sealed properly, it will also make an engine cough and misfire |

This should not be your issue. The only other thing that may cause an issue on your ignition side is your DFI module. Other than that I would be looking towards the fuel system.
Using a timing light as an indicator you should be able to check the ignition system for issues by testing each lead and watching for any indications of missing or erratic spark. |

| got it fixed checked everything, filter pump then realised my coil pack bolts have come loose and the module would come of the plate so i started the car and wiggled them and it caused the car to come to a point of nearly stalling so backfiring is fixed :) |

Yes, he's being a wise guy. The VN V6 only has 6 plugs. With any engine, you can easily find out how many by tracing the ignition leads. In the case of the VN, it's a block of "coil packs" at the front of the engine, leading off to 6 spark plug leads, each of which disappears behind the exhaust manifolds on the sides of the engine. Here. the only dopey question is the one you don't ask that brings you unstuck |

3 things you should look for first; first of all, open the driver's door wide, parked in a quiet place, and turn on the ignition. You should hear a faint buzzing noise. This is the fuel pump. If you don't hear it, check the fuses and relays, then the pump.
The second thing is the fuel pressure regulator. it's a small diaphragm-type arrangement at the back of the intake manifold, It will have a vacuum lead hanging off it and the fuel line going through it. Connect a small vacuum lead to it and suck on the lead. If it resists too much, replace it. As the name suggests, it's meant to regulate fuel pressure to the injectors.
Lastly, check the fuel filter. This is an inline filter with a metal barrel about the size of a Coke can. When you disconnect it, remember to point it away from yourself, as residual fuel may squirt back at you. If this is choked up, it will also cause trouble. It's under the car, about 1/3 of the way to the engine. A car sitting idle for some time may have any crap settled in the system.
If you find that the fuel filter is clogged, replace it and cut the old one open. This will tell you what's in the tank other than fuel, and whether more work has to be done to clean out the fuel system. |

He may be just misguided,the VN spark plug fires twice,once on compression & once on exhaust,this bit of a knowledge often confuses non-car people. |
