Been meaning to join for a few months ... finally a bout of insomnia coincided with enough patience to fight the registration process! I must be getting old! Technically I don't own a Rav-4 ... My wife bought a beige 02 reg 3dr nrg auto (4.2.0?) in early 2019 ... I took the gearbox ecu out when the box started behaving erratically after 3 months and sent it away for some replacement components and re-flashing - apart from a recent issue (cured by changing the auto gearbox oil and filter) it's been really great ever since. In mid 2019 my daughter started learning to drive (again, this time opting for auto) in it. She liked it so much that she bought a p reg 3dr auto (4.1) in early 2021. The only issue was (and still is) a clinking sound when manoeuvring on full lock (salesman thought it might be CV joints, but had taken it as a trade in and didn't know the model). I suspect it's the middle clutch not releasing the 4wd so the wheels can turn at different speeds - it is not present when manoeuvring on soft surfaces. Other than the fuel consumption being painful and the E5 fuel being silly money, it's a great car- and for £800 with less than 60k miles on it, an absolute bargain (though it needed 4 new tyres straight away - one must have been the original spare as it had almost full tread and a 96 date code!). Hopefully she'll pass her driving test (when she finally gets to take it, booked in June, December is rapidly approaching!), though I don't know if she'll be able to afford the insurance or the fuel ... Hi. Recently bought a 2002 auto. What symptoms or things were happening when you said the auto box was behaving erratically? Thanks Sorry for the slow reply, tried to log in on my laptop and struggled with the password ...
Erratic shifting is the big giveaway. Sometimes it would hold second up to 50mph, even with little acceleration. Sometimes it would appear to start in second (or maybe even third) and crawl forwards when you tried to pull out of a junction - that was a bit scary at times!
The most noticeable issue was a clunk if you changed to reverse and didn't pause for a second before lifting off the brake ... This may be a permanent issue now and may not be 100% related to the gearbox issue, just an effect of the mileage (a bit over 100k).
Recently it started dropping out of gear - that was likely due to the transmission oil / filter needing replacing (I suspect loss of hydraulic pressure to hold it in gear), so is probably separate (though having the oil & filter full of bits of metal shaved off the gearbox from rough changes probably didn't help!).
The ECU reprogramming / refurb appeared to fix it, but after the recent transmission oil & filter change it appears to be playing up again. Hopefully I'll find where I put the lifetime guarantee soon as it's MOT is nearly expired ... I'd like a route to fixing the gearbox first.

Our original RAV was an ‘02 4.2 that developed the ECU failure at something over 80K miles. ECUtesting in Derby sorted it and it was then perfect until we traded it in for a 4.3. One thing that I did learn from the experience is that if the car continues to be driven with the fault then the gearbox will very quickly destroy itself resulting in eye-watering cost for replacement (if such is possible from Toyota; probably not at the age of these cars now). It’s interesting that you say you had the ATF and filter changed since, AFAIR, Toyota didn’t recommend changing the fluid except in extreme operating conditions which seldom occur. There’s also a school of thought that says changing the ATF risks dislodging sediment in the box’s oil ways that can damage the internals. I’ve only ever changed ATF in one of our Saabs and that caused considerable problems that required the dealer to carry out three further fluid changes before the box performed as normal. In any event the 4.2’s gearbox problem was due to a fault in the Gearbox ECU hence re-flashing it effected a cure. |

Our Spanish 4.2 is now in semi retirement. Now on 280000 kms she deserves a little TLC and all those car park nicks and scratches are going to the spray shop when we get back. The 4.3 here in the UK is still going strong and with only 43000 miles on the clock and no faults, I have no inclination to change it. The new little Ignis is surprisingly good but we have had a paperwork nightmare trying to get the tow bar legalised, and then they fitted a 7 pin socket instead of a 13, so back to the drawing board and a possible bill for nearly 500€ to replace the socket!! Mental. There is in existence an adapter from 7 pin on the car to 13 pin trailer, but you do not get some of the 12V to the trailer ( such as fridge connection in a caravan) Yes, thanks for that but the rules in Spain mean we have to have the reverse and fog lights fitted when towing behind the van, (more than 750kgs) and that doesn't come with a 7 to 13 adapter. Our garage has come up with a cheaper solution now, around 250€ so we plumped for that, and it will be ready when we get back to Spain and in time for the Christmas jolly with car on tow. |

Seems to behave and change gears ok. I noticed on kickdown tonight that it revved up to almost 6000rpm before changing down and then down again when I eased off a bit. I was pulling away down a M74 slip road onto the motorway, and from a standing start. It surprised me that it took the engine up to 6000rpm before changing.
I am a wee bit concerned that the ecu may or may not have been flashed.... so where or how can I get it checked ? It is an import - built in 2002 and entered UK 2004, and the spec seems to be NRG but tgh I don't know much about it or the 4.2s.

There's no way of knowing, Ian, unless you have paperwork. However, if you remove it and send it to ECUtesting, they will check it and if it is OK, they'll only charge a nominal fee and send it back (but check their website as it's been a while since I used them). The gearbox ECU lives behind the glovebox and is easy to remove as long as you have bits to fit the security bolts. Also it's crucial that you follow ECUtesting's instructions for first-time running when you refit it. 👍 |

Well worth the money! |

I was just talking to the Toyota salesman here in Spain today and he tells me that the latest edition of the Yaris Cross is more powerful, and also has a chain timing belt. Tempted myself as just sold our house here and will have some spare cash. Don't tell SWIMBO!  |

Yes, the midlife update model has better soundproofing, thicker glass, wireless charging pad, a few more interior lights and the main one, the 130bhp and a few other nice upgrades.

I like it a lot, but not too sure about the hybrid part of the car. had a closer look at one this grade last week at a dealer event. I was very impressed and i think will be the replacement for the RAV in the future when it needs replacing. |

I was very impressed and i think will be the replacement for the RAV in the future when it needs replacing. It's what happened to me! My RAV was 15 years old and 115k miles. It never missed a beat, but I'm doing too many short journeys for a diesel these days. My Yaris Cross was a 2023 version with the panoramic roof and the 115BHP engine. Unfortunately, it was written off and because of the extended delivery on a replacement Yaris Cross, I bought the Lexus LBX which shares an engine and powertrain with the latest version of the Yaris Cross. I'm getting used to the gearchange now but, if I'm honest, prefer the transmission and change on the Yaris. It's very hilly where I live, and the "B" position was perfect for harvesting energy on steep descents. |

B position is great , I can come down 'Fish hill' near Broadway which is a well known steep hill , in B without having to touch the brakes , except for a small dab on the sharp bends.

I'm afraid that I always feel rather virtuous ( or maybe it's smug ) when I manage something like that. It's also brilliant for adjusting your speed in traffic on motorways. I think it did my driving a lot of good as I now tend to look much further ahead than I used to. The LBX doesn't have that facility, instead it has "S" ( Sports ) mode with paddle shifters on either side of the steering wheel. Instead of just pulling the stick back into B, you have to change into S then drop into S3, S2 or S1 to get a similar effect. I'd never use S otherwise as it's quite quick enough for me in Eco mode ( poor old bu99er! ) |
