Tranny question Bill?

[Power Hungry]

The transmission will default to 2nd gear any time it feels there is a problem with the low/reverse clutch assembly. Unfortunately, there are several things that could cause this and I'd be very hard pressed to offer a solution or even begin to tell you where to look.

My best advice... Call Brian's Truck Shop (870) 422-FORD (3673) and see if they might be able to offer some possible pointers. Because this issue could be either mechanical or electrical, you may have some hunting to do.

I wish you the best of luck and hope it's something simple and easy.

Thanks Bill. Been trying to call brian, He's a busy guy to catch up with which i understand. I guess there could be a line pressure issue there, but as far as mechanically how the tranny works, it works great. Shift fine and solid and doesn't slip. Pulled the pan last night and there were no material on the magnet, fluid was still good, I couldn't find any sticking valves in any of the valve bodies. I've read a couple post on rfi interference. Do you have any ideas on that? like alternator being good but causing interference?

I've never seen that, but doesn't mean it can't happen. It's possible that the MLPS (shift position sensor) is flaking out on you and I'll try to locate the tests for that and get them over to you. Other than that, I just don't know.

I'd really appreciate that Bill. I have been wondering how to test and what it exactly does. Thanks.

I talked to brian at bts finally. He thinks that since i keep getting a 720 code and something is interferring with the signal from that sensor. He recommend alternator so i test drove it with it unhooked and no problems. So i bought a new alternator and so far its been good. He was great to talk to and really helpful with information.
