Thread: Pending Transmission problem?

G'day Paul,

About the only advice I can offer on this is that with previous auto trans on Rangies and Kombis, when I have had problems like you're describing, is to take it to an auto trans specialist and get it serviced by someone who knows. It has always sorted out the little irritating things. But having said that, none of those were electronically controlled transmissions, like I understand the ZF in the P38 is.

But it seems to me that a good service is worth it for your car, especially given the nature of the work that Hardy put it to. It could well be a few hundred buck well spent.

Thanks Willem.

Can anyone suggest a transmission specialist in the Canberra region that knows P38A's please?

Cheers, Paul.

You can still service them yourself, you just need to devise a way to fill it with oil, as there is no fill tube, only a plug hole.

The best way that i saw someone do this, was a sealed container with the measured amount of oil, there was a tube coming out the bottom which had a fitting that screwed into the plug hole in the gearbox pan. In the top of the container was an air fitting with a tap. When the container was slowly preasurised, the gearbox filled with oil. Then replace the plug without spilling too much.

Tried cleaning the MAF sensor yesterday to see if it made a difference - it didn't.

Carefully pried off the front mesh on the MAF, sprayed the "hot wires" liberally with isopropyl alcohol, let sit for a few miutes and then gently dried it with indirect compressed air. Reassembled MAF and went for a drive.

Still jerking between gears and relucant to engage reverse at times. Went for a run in the dirt and mud to give low range a work out and noticed that 1-Low wouldn't engage on a couple of ocassions. Seems the shifter just couldn't get to the notch if that makes sense.

Wondering if the shifter has moved or the cable is worn/stretched. Probably not the main problem but a possible side-effect?

Guess I'd better add this to my ever-growing list of stuff to get checked.

Just as well I love my Rangie more than paying off my credit cards...

cheers
Paul.

hi and low is changed by a motor (and a controller under the pas seat) so no cables to stretch. It has a switch in the gear shifter.

Quite possible. I had the same problem and had to adjust the cable into the switch. In theory, one needs the right tools but I found I could adjust it (under the car). I slackened off the nuts and moved the arm, adjusted the nuts, and retightened them.

I understand what Andy is saying but mine must have been right on the verge of the correct position.

Thanks Andy - think that was the thread I got the idea to clean the MAF from. That bit was easy 'coz I know where the MAF is. NFI where the TPS is though.

The previous owner told me that the tranny was rebuilt about 35,000Km ago so the new/renewed components are probably a good place to start checking.

I'm biting the bullet (and probably a significant bite in to the bank balance) and sending it off to a workshop next week.

Hoping they can change the fluid, filter and adjust the cable and all will be good again.

cheers
Paul.
