Autobox problems - SOLVED :D
Hi All,
I have just discovered a nice low mileage R75 -99 2.0V6 auto for sale for a nice price. The problem is that the seller write that the autobox has a problem. It slips out of gear while driving. Does anyone know what the possible cause for this can be? Migth it be repairable or does it need a new/used gearbox in good condition? Thanks for answers Last edited by beinet1; 3rd September 2012 at 06:12.. |

Auto Box
Almost all problems with the Jatco box have either been:
1) Fluid never changed, dirty or wrong fluid used. As it is not expensive to change the fluid, in the UK, this is usually the first thing to try. 2) Faulty solenoid/s. These can be tested fairly easily in the car, can be replaced with box 'in car'. 3) Cracked Revese Piston. (Doesn't affect only reverse) I think you are indicating it is a 1999 model and the early cars up to 2002/2003 frequently suffered this problem. Jatco have modified the part but that doesn't help as you still have to buy the parts ! It is probably the only other fault that can be corrected with 'box in' though needs careful assembly before replacing. There is a lot of information either in a search (see task bar above) or in the 'How To's. There is a complete description re the revese piston if you do a search, with step by step photo's. A search should also produce info on the solenoids with testing values given. Don't know what Km the car has done but the Jatco box is fairly robust to well over 200,000Km with the above exceptions. By the way the fluid should be changed every 4 years or about 100,000Km but more frequent changes are advisable. Bear in mind only about 60% of the fluid will be changed after a drain & refill. My box had a change at 50, 000Km and will be done again at 100,000 Unless the price allows for a second hand box replacement (late 2003 on) the only alternative is for a transmission specialist to diagnose the problem before you purchase The solenoids are not particularly expensive to replace but a cracked piston costs around £500-£600, to replace in the UK, by a specialist. The parts are only about £70 ! ! Thing is they usually tut, tut, tut and tell you you need a recon. box but that has probably only had the things mentioned here done. Profitable business ! ! If you need parts from the UK only buy from:- www.sussexautos.co.uk Tel:- (44) 1323 848886 Please let me know how you get on Dave

Dave's advice above is spot-on. Simon.

The seller just told me that the box slips out of 3. and 4. gear. The car has only done 76000km/47500miles and has all services done according to the seller. I am not sure that the fluid have been changed but possibly not as the service recomendation is 100000km. I am thinking that this migth be a bargain if I don`t need to change the box. I am able to do all the above mentioned operations by DIY. |

As Dave says, you won't need to change the gearbox. People only do that because

Hi all,
I got the car home yesterday. I was able to drive it by locking it up in 3. and use the throttle gently. It seems that it drivers like it should through 1. 2. and 3. When shifting up to 4. it just "pops" og "slips" out of gear. I have to put the selector to P or N, stop and restart engine to get it moving after that. I got an "EP" showing up in the display during this. I have not done any checking yet, but as you say, an oil change would be the first resonable atempt. Will try to carry out this someday the next week. I wall also check the solenids resistance with a multimeter. I guess that a resistance check of the solenoids will only reveal "burned" solenoid coils and not a "sticky" solenoid valve?? If this not helps, I will go for a reverse piston replacement. What would be the typical symptoms of a cracked reverse piston?? Thanks for all advice so far Last edited by beinet1; 3rd September 2012 at 11:48.. |

Hi all,
I have just talked to the garage which conclude "replace box". They have done an oil change without any help. Seems like I have to proceed with checking solenoids and possibly replace the reverse piston. I have sent an parts enquiry for the reverse piston parts. As far as I know, I need: - JF506E.PIS01 - JF506E.CIR03 - JF506E.ORK01 - JF506E.PIS01 Can anyone confirm this?? Does anyone know where I can find a part list for this gearbox? Thanks |
