problems with an auto vectra box after fitting a new engine
Discussion
car is a 2001 vectra b
a lad i know has fitted a new engine but now has a problem with teh auto box as his car wont drive. it did for a couple of seconds after fitting the new engine but now its given up so hes asked me to help lol
im more than happy at all things mechanical but never messed with an auto box so need some advice
when the engine was taken out the torque converter chucked its fluid all over the floor
hes been told it could be the pump so my question is does the box need priming ?
any advice greatly received

If the torque converter chucked its fluid out, he must have left it attached to the engine during removal (the torque converter should be unbolted from the flywheel/drive plate through the starter aperture and left with the transmission)
If he installed the engine to the transmission the same way, he is likely to have damaged the front pump unless great care was taken to align the pump drive.

why do you ask ? as the engines are all the same regardless
cheers for the replys

after speaking to him they pulled the torque converter out with the engine. can the pumps be replaced ? if so where are they ? are they in the box ?If he installed the engine to the transmission the same way, he is likely to have damaged the front pump unless great care was taken to align the pump drive.

No, not always, some have mechanical and electronic adaptions to work with an auto.
I'm not an expert on this engine and not pretending to be, but if you were to put an engine management ecu from a manual car onto an auto, odds are it would cause operational issues.
Additionally some automatic engines have mechanical differences to support the use of the box.

cheers for the input but the x20xev in the vectra is the same in both, the cars original wiring loom was used so its not an electrical fault
Actually, rather than electrical, its more a software problem, yes the looms will typically be different for the 2 cars, but auto boxes are now electronic and have been for a while, the box will typically have its own ECU.The EMS and Gearbox controller will communicate each other, with the manual there is no ECU and so is not expected to be there, this can cause operational issues.
There is a bush in the back of the crank on the manual engine that isn't there on the Auto (or is it the other way round..?) - plus when refitting the TC if it doesn't line up right with the pump then it will destroy the box in seconds.
Not long swapped an X20XEV - it was in an Omega, but same applies. I was offered loads of manual engines but held out for an Auto one deliberately.
Looms and ECUs are different between manual and Auto engines - think you can a Manual engine off an Auto loom but not the other way round.
Given it spewed all of its blood out, then i'd say the box/TC are fubarred.

engines are the same mate regardless of manual or auto and i know the looms and ecus are different hence me saying the original loom was usedNot long swapped an X20XEV - it was in an Omega, but same applies. I was offered loads of manual engines but held out for an Auto one deliberately.

whilst i really dont want to sound ungrateful i know how the electrics and ecu works between an auto and manual i just need advice on the pump issue
cheers
