hey jcm how you doing i hope good because i need some serious help i bought and completely rebuilt a 2000 romeo 5.4 and put it in my 97 f150 4x4 where a 4.6 once resided i followed your swap tips to the t it runs awesome my problem i ran into is now the auto tranny is downshifting through the gears the instant i let off the throttle pedal which is pretty scary at 70 mph i did use the 4.6 convertor but i dont plan on beating my truck just driving it to work and i also have the stock 4.6 ecm any help or tips would be awesome
thanks for your time mike

DaXx,

If you look closely you will find a rubber plug on the drives side of the engine block. It lines up with the torque converter bolts and allows you to use a ratchet on the nuts/bolts. Again I am sorry for not seeing this earlier. P.M.s will notify me directly of any activity in my account.

JMC

Sorry for the late response. Hktdad, I would use the 4.6 PCM and the 4.6 harness. The 5.4 uses a Coil on Plug ignition and the 4.6 uses a coil pack. I cannot be sure that he 5.4 harness will work with the 4.6.

Hello JMC you will most likely be one of the people to respond to the thread i just posted so i figured i might aswell ask you in a message so i get notified when i get feedback. The 4.6 Wvin, what would be the best way to go about removing the torque converter/flexplate bolts.. ive tried a ratchet but it wont fit between the oilpan and bolt, wrench just doesn't have enough of a bend in the box end to slide over the bolt...would it be easier to just pull the torque converter with the engine? i was told there is a seal that would have to be replaced if i did so, how hard would that be to replace and what seal would it be? thank you a Million times over, for all your help in getting this truck going

dear mr jmc, i have a 97 f150 with a bad 4.6. i was thinking about putting in a 5.4. i was told i could if i use the 5.4 wiring harness. will that work with the 4.6 computer? if it will all work can you send me detailed instructions on how to do this? THANKS

No problem. FWIW pick away.

JMC

Dear Sir. Thank you for all theinput on the 5.4 swap. have a few questions i would like to ask you. is it ok to pick your brain?

Don't expect it to hold up to the power of a 5.4 if you beat on it.

hey just had a queston about the ford manual tranny, i have heard taht they don't hold up under more than stock power. i am looking at doing a lightning engine swap and i want a manual but if it won't hold up i would like to know before i'm in too deep.

hey if you could help me out it would be fantastic. i just posted some pictures in my thread called "let the swap begin" i'm haveing a few problems with my wireing check it out see if you can help thanks `chris
