If you have a manual Rav4 can you:
Get the full trans code off the chassis plate, and if it says E250 (or anything starting with E):
1)write down the full trans code eg E350F-06A. Or better yet, take a pic of the chassis plate.
2)Check whether the end cover on the gearbox is a black pressed steel cover (like shown below) or a cast Ali end cover.

3)Note year and spec of rav4 eg 1996 RAV4 L 3sfe 2wd.
4) Tell me what revs you are pulling in fourth and fifth at 100kph, and tyre size so I can work out overall gear ratio. If you can tell me what speed you are doing at say 3000rpm in each gear that would be super awesome and allow me to confirm the info below is right or not.
Thanks in advance for anyone willing to spare 10 mins to help out.
These are the supposed ratios I expect to be found based on various internet sources.
