Hi there,
My trusty 1992 surf SSR-X auto has suddenly developed a problem with the auto box. http://www.hiluxsurf.co.uk/forums/im...lies/knife.gif I have been using it this summer to tow my caravan. It has coped well but I've noticed the gearbox is getting hot, noticeable when going up hills as the radiator fan kicks in. I guess towing causes the torque converter to work harder, heats the ATF more, hence this heats the radiator (as the ATF is cooled through pipe in bottom of rad) and fan kicks in. Also its getting hot in the cab due to heat rising from the transmission... melts your maltesers! (must fix air con!) So I have bought an oil cooler to fit to the ATF pipes before they go into the RAD, as recommended by the caravan club of all things. Thought I'd better fit an oil cooler to avoid problems with the box overheating.
So just one week after changing the cam belt and front discs/pads, and still waiting for my oil cooler to arrive.....
Last weekend, I tried to reverse still with caravan hooked up, got no movement. In fact engine would not rev above 2000rpm, so something felt wrong. revd in neutral, it creeps forward. Cannot move the H2-L4 lever without serious effort with engine running. So i unhooked the caravan and drove up and down for 5 mins, seems fine in forward gears. In reverse, it will now go back, but you have to rev it, and then it will judder back. It feels like it is trying to go forwards at the same time as it trying to go backwards. Ie. it jumps back a foot or so, then stops abruptly and bounces/rocks forward slightly (as if it were in park or something). Definately something wrong with reverse. So I checked the ATF, which was on the HOT low level, so topped up to high line. Hasn't cured it at all. The 4wd button engages the 4wd properly, tested this out by going up a very steep farm track, no problems going forward. Also i changed the ATF about 18m ago, done maybe 8k miles since.
So having read a few threads on here, saying it could be the selector linkage needing ajdustment,( I hope so) or could be a burnt or worn reversing cluctch in the auto box. In which case its a specialist repair or recon box. Has anybody had this problem and been able to fix it? Am I wasting my time fiddling around with this, or should I try and get a decent replacement auto box for it?
Has anybody on here changed an auto box? It doesn't look that simple to me, its a big old transmission!
Any advice really appreciated - especially from anybody who's had the problem and been able to fix it without having to change the transmisison.
Thanks and all the best everyone.
