manual transmission probs

[Guest Close Guest]

G'day there all , and thanks to the board for allowing me to become a community member of Pradopoint.com.

I have an issue with my 2001 prado gxl 3ltr turbo diesel, a couple of times the shift has jumped out of gear ( 2 wd ) from take off , into nuetral . Then on the weekend the damn thing jumped out of 2nd gear ( 4 WD ) low range on a slight incline , slippery grass - shailey type ground . Quite a noise it made as well , being under load and all.

The other day i did a test and whilst increasing speed in 3rd gear i managed to pull the shift out of gear into nuetral ( under load ). This i believe is not supposed to happen , so the first thing i am going to try is use a thicker oil , say 75/85 castrol and some mollybond gearbox grease.

Has anyone had this happen to them and what did they do to rectify the problem, if they had to have a fully rebuild of the gearbox = how much did it cost them . My Prado has 212,000 klm,son the clock if that helps, cheers and thanks once again for the opportunity to join this site.

Gavin3lt,

Sorry to the bearer of bad news but thicker oil wont help, I had a older model Hi-Lux that use to do the same thing. The fork selectors, bearings, spacers and associated parts have had the bomb and the gear box will need to be rebuilt. The Hi-Lux cost me $1800 back in 94 so knowing Toyota and the Prado having a bigger gearbox except the cost to be high.

Once again I say sorry and wish you good luck.
