Selespeed Gearbox Gears 1 & 2 Problems
New to this site so a big hello to everyone, i'm hoping someone could shed some light on this issue i'm having.
I've got a 2001 156 2lt Selespeed which has done about 82k miles, I've owned the car for a year but only over the last couple of months started to get this problem. Please bare with long explanation:
Scenario is, about to use the car one morning (or afternoon) for the first time in a couple of days, turn the ignition on, car starts fine etc. Gear is in N (if memory serves me right).
After a minute or so fiddling with the radio, giving the engine a quick bit of time to move oil around etc I put the gear into 1st (in gearbox manual mode). The gear display on the digital dash flashes 1, so I pull away.
What happens next varies slightly, but usually the gear display jumps through gears, like 2 to 5 to 3 to 4, usually ending up in 4th and without shifting up or down the gear box it automatically goes into 2nd (baring in mind i'm meant to be in manual gear select mode) with the display still reporting im in 4th.
So i'm physically in 2nd gear but reporting 4th, I try to shift up a gear to go into what I think would be 3rd and it wont let me, I have to shift down a gear which will make the gear display go to 3rd and the physically gearbox shift up to 3rd.
This exact same thing happens if I was in 2nd gear.
This ONLY happens in 1st or 2nd gears, 3rd 4th or 5th gears (and reverse) have no such problems.
So lets say i was driving along in 4th, all fine, can shift through gears 3rd to 5th fine, come to some traffic lights in an orderly mannor to a stand-still keeping foot on break (or handbreak on), the car shifts down fine and gets into 1st, then what happens here varies, the digital display usually displays random gear numbers, and sometimes reverse (which sets the reversing alarm off) and the physical gearbox clunks (well, shifts) through gears, what gears I dont know as the dash is all over the shop.
And sometimes, the gearbox red fault light comes on, though this has usually only happened when i'm shifting from reverse to 1st in quick sucession like if I was trying to park the car.
From this point the only way I can usually pull away is to go into N, shift up to 1st and quickly start to pull away before the whole scenario starts again.
Sometimes this is more servere then others, usually when the car is cold or not been used for a while its very irratic, other times its not so bad. But this is becomming very annoying. Espceially driving along in 2nd and suddenly hear the reversing alarm come on, the gear display saying im going backward and in fact im in 2nd gear going forward.
Funny, it's only happens in 1st or 2nd, with other gears acting fine as they should do.
Putting the gearbox into Manual or City mode as no effect, and the same problems continue.
In a few instances over the last month (perhaps 4 times) the car has been operating absolutely fine, so i've (stupidly) shrugged the problems off, until this last couple of weeks when it's becoming very servere and happening continually.
Sorry for the very long rambling post, I'm just trying to explain what i'm continually getting in as much detail as possible.
Can someone shed some light on any of this? Is there things I can do/check to help?
