Did you ever get a new TCU? I was wondering if it fixed the problem...I recently bought an XT6 with the same exact symptoms (no power light or 1st hold-down, only 3rd gear and reverse), so I'm hopeful you can tell me that the TCU is the fix. -Scott

Thanks. Yes, the black box is not there. In its place is is this silver multi-sided thing with a bunch of terminals on it -- like a transformer or something. I have a picture of it, but I'm not sure how to post it. On the fuel filter question, I'm trying to figure out which are the lines I would connect to the filter, since right now they are going directly to the engine and the filter is missing. I noticed three lines coming out of the firewall, two on top, and one centered below them. -Scott

I recently purchased an xt6 up in L.A. and the previous owner had some problems with the power controller "burning out" -- not sure if that's exactly right, but that's how he put it. Anyway, he took it to someone and they installed some weird non-original part . Does anyone know how this works...it seems to steer just fine, but I'm thinking I'd like to try returning it to original equipment. Also, the guy removed the fuel filter. There are three lines coming out of the firewall directly to the engine. Is there a diagram online I can reference to make sure I'm hooking up a fuel filter properly? Thanks for your help. -Scott

I recently purchased a 88 XT6 that's a FWD automatic with the 4-speed EAT . The power light for the transmission (the one on the dash) doesn't come on at all, even when starting car. The 1st gear hold-down button/light don't work either, and the car only seems to have 3rd gear when in 'D'. Any ideas on how I should approach this problem? Thanks for your help. -Scott
