Reverse lockout solenoid

[Flyn]

On the way home from work today, I stopped at a gas station. When I was leaving, I tried to put the trans into reverse but it wouldn't go past the reverse lockout. It felt just like it would if you were trying to shift into reverse while moving forward faster than the lockout allows. I pushed the car back far enough to engage first and drove home. Forward gears are fine.

I tried to put it into reverse again when I got home but no go. I'm assuming this is the reverse lockout solenoid misbehaving since the trans seems fine and just feels like the lockout is engaged.

Anyone else ever have this issue? If so, what did you do? I'm going to jack the car up tomorrow and make sure the solenoid is connected. Maybe the wire came loose or a fuse is blown. If it's OK, I'm guessing I'll have to replace the solenoid?

Here's an interesting write up on the Tremec T56 that I found while researching this problem. Very in depth coverage of the trans. It takes a while for the .pdf pages to load.

Pull forward into parking spots, that way you're facing out


Sorry Cliff, can't help you on that one.

Check the fuses. I forget which one it is, but it has the O2 heaters on it too.

number 8 fuse maybe?

Jimbo - No, that was the Mercedes.

Dan - Thanks. On modfords, a guy mentioned fuses 17 and 35 so I will check all three of them.

+1. This happened to me when I installed my mid pipe and had to extend the O2 sensors. One of the wires melted on the pipe and the fuse popped. It also controlled the reverse lockout. thats what it was.

I tried reverse this morning. Still no go. I pushed the car out of the garage so I could center it to jack it up. Put it in first and pulled in. Tried reverse again and it went into the gear easily. Tried it a couple more times and it worked fine. I took the car to work for a test drive and to drop off my guys' paychecks. Get to the shop and it won't go past the lockout again. I brought the car home and put it back into the garage. Jacked it up and I'm waiting for it to cool so I can check the wires on the solenoid. I'd guess it's not a fuse since it did work earlier. Once a fuse fails, it wouldn't work again. If it's not a loose wire, I guess I'll have to replace the solenoid. Anyone done this? Plug in or major project?

Piece of cake. Its hanging right there off the tailshaft housing on the driver's side.

Thanks, John. It's a warranty repair so Sutton threw one on for me. Picking the car up today.

If you put a little muscle into it you dont need the reverse lockout solenoid. When I did the T-56 swap in my GT I didnt even bother making my own pigtail thing to make it work I got used to just putting a little more effort into making it bypass it. Just an FYI. Glad your getting it under warranty tho

I didn't want to weaken the springs and accidentally go into Reverse instead of 5th. That would ruin my day.

It really doesnt weaken the lockout at all. Mine stayed the same the for 6+months. Most guys that do the swap run it without it forever. The throw to reverse is really far off from 5th IMO but better safe than sorry in your case. I'm glad your getting it fixed cause with the luck I have if you didnt use it like me it would soften up and you would hit reverse on accident :lmao:
