Dear Nairaland Car gurus, please come to my aid as fast as possible.

I just got a 2001 Rav4 and the vehicle is giving me headaches. After purchase, I had my mechanic drain the transmission fluid inside and replace with Toyota Type T-IV.

I decided to take it with me on the family Christmas trip and noticed that it wouldn't go beyond gear 3 (80km/hr at 3100rpm). Even when I fire up to 4000rpm, it still wouldn't engage gear 4. All through the trip, I left the speed at 80km/hr (3100rpm).

Apart from that issue, I noticed that the Reverse gear when engaged would sometimes give noticeable jerks and the accelerator depressed. Other times, it moves fine.
I've tried using a scanner to read possible codes but to no avail (scanners says "link not found". I've read online that this model is plagued with transmission issues but that can be resolved.


I'd like your opinion on what's going on and how to rectify same.
Many thanks.

Hello @earthrealm and obekediamondfuto, I am happy to report that my prolong gear issue was resolved today. I am so elated so much that I paid the guy more than we bargained. All along, it had been an electrical wiring problem.

He traced/tested each port on the ECU and wires from the valve body connector for continuity. Did some corrective works etal. Long story short, vehicle entered 4 and 5 o. I entered Lagos/Ibadan for testing and I was more than happy. At 100km/h, my rpm was at 2000 or so. I hit 120 on the long bridge, hit the cruise control button and eased off my leg on the throttle. Baby boy was just sailing.

Overdrive button now functioning. Return trip, I hit the O/D button and I could hear the high pitch from the engine. O/D on again, and I was back to 4 and hit 5 before reaching Berger.

By the way, I serviced with T-IV after the electrical work finished before going for the test-drive.

Thank you so much for your help.

Hello. I've been having similar issues. If I was in Lag I'd have tried the guys you used to help resolve your issue.

When I had this similar issue, scan said one of my coil has spoilt, the car started working perfectly after changing the said coil
