Help Selespeed Help

Hi guys,hope someone can help. We have a 2003 (build tag June 03) 147 2.0 TS selespeed and is it is giving us no end of grief. the car while driving will go into N, sometimes we only get
1st and 3Rd gears with no reverse and while driving it will fix itself. other times cant get 4th gear jumps from 3 to 5th. We have AlfaDiag and sometimes get the error codes P1741 P1742 and P1753?? (Fiatecuscan). Things we have done to fix.
1. New Accumulator
2. New pump
3. 3 new Potentiometers
4. Gearbox oil changed and system flushed.
5. Performed all the EV tests
6. Adjusted the clutch rod to correct specs and recallibrated. (full EOL) in both alfadiag and fiatecuscan.
Now dont know where else to turn any help and advice would be most welcome.

Hi ace34t,

Sorry no real help just a suggestion when my 2002 147 Sele started acting up I checked around and took it to McCarrolls Alfa in Roseville they are a dealer so you will pay but if you go to • Index page & join and search you'll find there's some reportedly quite good Indies in Sydney to take your sick Bella to.
Good Luck

Error Codes P1741 and P1742 relate to the Gear Insertion Sensor and the Range Insertion Sensor respectively.
This will be what is causing your car to slip into neutral. Change these and it should be fine - you need to do an EOL Calibration afterwards making sure that the clutch rod is position correctly (which you say you have already done).

When fitting the new ones, you need to make sure that they are twisted to tension otherwise you will get a false high reading level and it won't work. Here is a link to where the sensors are located:

Hope that helps
