While I'm waiting for the fuel system to be finished, I might as well address some other things. My car will shift into all gears only if aligned properly, i.e. if I put it into reverse first. Otherwise, it'll shift into one bank (1st and 2nd) but not the other (3rd and 4th).
I don't know if it's a matter of wear in a bushing or something or something out of adjustment. Thoughts welcome.
Gordon.

The P5 manual box is well proven and dates back to the P1's of the early 1930's and then goes on into the Series Land-Rovers till 1980's. The change should be good but it is not made for fast changes and is anti-force and will resist this! Slow but steady is the norm
Difficult gear changes if not down to clutch spin/drag is either through wear in the selectors or poor adjustment of the remote change.
Before doing this it is best to change the oil (when hot) and refill both box and overdrive with good quality 20/50 Multigrade engine oil.
Examine old oil - it may well contain silvery or golden fine partcles but hopefully not bits of gera cogs and ball bearings

Hi Phil; I have a 4-speed manual gearbox also with problems shifting. The problem with my remote selector is not bad adjustment but rather that the lower bushing where the bottom of the gearshift stick attaches to the selector rod to the transmission has totally rotted away. I have a spare tranny and the bushing is also rotted away on that one. I have tried previously and been unable to find this part. Do you know where i can get one? This can't be a rare problem with the manual, but I haven't seen it mentioned before. Thanks, Ken
PS The gearbox and clutch otherwise work fine.

It has been covered before and part is NLA apparently - although aP6 type may fit?

New information as of today: the bushing at the bottom of the gearshift lever looks almost pristine, fits squarely into the shifter rod, so that isn't the problem. Whatever it is, it's mechanical, a question of alignment, because it does it without the car running. If gears one and two are aligned, three and four aren't, and I have to move the shifter all the way to the left and right a few times to get the other two gears to align.

Selector problem? Refer to WSM

Update on my 1963 3-Litre 4-Speed w/overdrive. The symptom was that I had to hold the gear-shift lever in 4th gear because it kept popping out. I suspected a broken synchro, but there's nothing obviously wrong inside the gearbox (upon opening it up and examining it closely). So, here's the question. Is it possible that there's something in the overdrive that's popping it out of fourth gear?

Thanks, Phil, for all of your responses.
I've just finished the gearbox removal, rebuild, and replacement process. If anyone is contemplating this job, let me know and I can pass along a few thoughts, having succeeded despite a few rookie mistakes along the way. The clutch replacement was the easiest part of the job, the clutch-spring replacement the most difficult.
Gordon.

Came out of my Winter doldrum determined to get the P5 on the road. As far as this thread is concerned, I continued to have problems shifting (4-speed), having to hunt for the right gear, with frustrating (and scary in traffic) balking. I'd assumed (as had a professional shop last Summer), that the problem was with the selector fork, and I did endless tinkering with only slight improvement.
Today I looked at it anew, noticed that the reverse stop seemed to be adjustable. A quick adjustment solved all my shifting problems and each gear is now discreet and easy to engage. I want to get the word out because I know other people had had similar problems.
Otherwise, a brand-new servo (Lockheed 7, well worth the dough) has solved my brake problems, and the gearbox I rebuilt last Fall seems to be holding up fine.
A good Rover day.
Gordon.

Glad to hear your shifting is working well.  I'm still looking for a replacement for my lower selector rod bushing. Anyone have a source? Here's a picture-the rubber part of the bushing has rotted away.  Ken  |

You might try the same part from the other cars that share the same gearbox? Namely Land Rovers?
Perhaps the bushing from an unrelated car that has good parts availability could be adapted? I know that MGB/Cs have new plastic bushings available, and they might be made to fit with some modification?
Maybe an O-Ring of the right size would fit?
Just throwing out ideas here...

Thanks, those are good thoughts. An O-Ring wouldn't work, but I'll look into related parts from other cars. Also, does anyone have a used selector rod complete with a good bushing from a P5 manual gearbox 3-litre that I could purchase?

Here's a picture-the rubber part of the bushing has rotted away. Ken I had the same problem, fixed by epoxy gluing on a lump of hard plastic to the end of the gear stick and then turned it into the correct shape in a lathe. |

For an update. Jon Wadhams now offers a reconditioned lower gear-lever section with a new bushing on it. You send him your old piece to be reconditioned. I'm waiting for one to be done and returned. Hopefully it will drop in from above and fix this shifting problem. The circled area is where the new bushing is applied. Attachment Deleted |

The refurbished lower gear shift lever bushing from JRW has been fitted and works well. But now I have discovered that both of the selector shaft bushings (one in the casing at the front of the selector shaft and one at the rear in the remote support casing) have rotted away. JRW sells a gearbox selector shaft bushing now and I am going to order 2 of them, but does anyone know if the same size fits in both places for this?  |
