Engine/Transmission (1998.5 - 2002) Need help please with trans swap please

[TJSHOTROD]

My truck will not run after swapping out the nv5600 for a fully built suncoast. The engine will run fine on a breakout box but will not run with my electronics hooked up. PLease give me all your suggestions as I need to have it running by 5/2 it is very important. Thank you for any help.

I'm thinkin your ECM and PCM don't like what you did--it could be just the PCM, but I'm not sure--did you call J&H--chris

 

[TJSHOTROD]

Yes they are doing the swap and they are thinking the same thing. I am just getting nervous and was wanting some ideas just incase that is not it.

J&H in redding? They pretty good guys? I am in Lodi, CA and am having a problem with my boost pressure which is on another post and was thinking about taking it up to them.

J&H are awesome guys--a very good choice IMO--chris

You are gonna need a new harness to get your truck to play nice with the trans. I do believe the ECM id different and the PCM is for sure.

To be safe I'd get both and probably the harness too, just like FG said----nothing more frustrating than changing one electrical part to find you need the other and then something else---good luck----chris

 

[TJSHOTROD]

They got it fixed thanks guys. The J&H guys are good I was just stressed out about it.
