Good evening experienced Nairalanders,

I have this issue that has been bothering me and which I need help with.

I have this 2000 Volvo S80 that has been doing well for years till recently. The issue is with the transmission. It starts normally, engages drive normally, and shifts to Gear 1, 2, 3 and 4 without any hitch.

However, the problem is when I have to stop or slow down after reaching Gear 4, it won't shift back to Gear 1 automatically. At that point, moving the car becomes a drag as it has to force itself to move (I guess from Gear 2 or 3) before it starts moving well again.

I have scanned it, and the only codes I get are P0751 and a P1618. The P0751 points at a stuck shift solenoid. I wonder if it is possible to change the solenoid or something. I just need some counsel on what to do.

Thanks for your suggestions.

Yes you can change it but it might be stuck because there is dirt clogged in it. Your transmission fluid should be dirty. The person changing it might have to drop the pan unless it is one of the external solenoid

Thanks for the response.

Do you have any idea of who is competent enough to handle such delicate fix?

Manually shifting the lever to the lower drive positions when such occurs to help you accelerate & avoid lugging the engine might help until you service your gearbox ASAP.

kindly visit mecheal excels auto care centre, plot 365 agege motor road, opposite vono plc mushin. or call 08026999465 for your services.

Just seeing this old thread.

I ended up changing the gearbox entirely back then. This was after I had replaced the solenoids and changed the transmission fluid, and there was no difference.

Thanks to those who responded though.

Meecheal Excel... time wasters!!!!!!!

It is a pity that my YouTube page isnt working. Try to prime the gear and tell me the result.

How to prime a gear:

1. Turn off the engine
2. Engage the gear in "P"
3. IN QUICK SUCCESSION (as in fast), engage the gear from "P" to the last gear (that is "1" and back to "P". Do this three times.
4. Start the car and move.

Tell me the result. BTW, this is not to say you wont eventually repair/change the gearbox.

I think it was between 120k and 130k then. This was in 2017.

Why do I have to really force my gear lever before it could engage the Drive, but the reverse neutral and park are just normal, but when I shift to Drive it will show neutral until I force it, and I che k my flood level it was on hot position what will I do
