Toyota Raider 2.7i Model 2001

Yep, Lyn got it again, I would not be alarmed, they do run hot normally.

As long as it has the right amount of good oil, isn't leaking, runs smooth, doesn't make noise/vibrations, and goes in and out of all gears normally, then I would not worry a wit about how hot it feels (unless it starts smoking/glowing red)

What do you mean by "getting hot". Is it getting so hot that you cannot touch the stick shift? Is the transmission getting so hot that the chassis undercoating is melting or smoking? Has the metal transmission chassis started to liquefy and sag from this heat?

"My vehicle gearbox is getting hot when driving on highway from Witbank to Pretoria..."

Is this your perception only or do others perceive the gear box as getting hot also?

It must be a very long drive between Witbank and Pretoria???

_{Sorry, just my attempt at some tongue in cheek humor}

As my colleagues have stated, unless something really bad is happening, smoking, melting, catching fire, oil vaporizing, noise, ect, all is probably normal.

Happy motoring!

It depends what you mean by hot. Too hot to hold you hand on is 70deg. C and it should be hotter than that. Smoke coming off it is over 200degC and not good (the oil will oxidise).

Hot is a relative term. I suspect nothing amiss if you have a quiet box.

The previous posts cover - how hot??

"New oil from Toyota agents...." may be the place to start your check. They may have used the incorrect grade of oil! Drain and refill with the correct grade of oil. Older boxes will enjoy a tube of Molyslip gearbox additive. The Teflon based additives also work well in gearboxes. Always drain the oil first and add additive before refilling. Look at the drained gearbox oil in the sunlight to see if there are metallic flocks in the drained oil .... tell-tale of excessive wear/bearing failure.

Looking at the year of the bakkie I guess you may have had it for a while or it's a second hand unit. Has it done a lot of towing? (Look at the tow hitch ball and mike it for wear if you need to.) You may have to replace the box or have it reconditioned.

I would never advise any one to put additives in a gearbox for it makes the sinchro cones slippery which cause gears grating and thus more wear.

Rather check with a good mechanic or better, gearbox specialist, to find out if normal red automatic transmission fluid will do the trick.

All the cars and trucks i had [even a Citroen] was run with automatic fluid in the manual gearboxes without any trouble.

Hi guys

Thanx for all the feedback...Surely the box is still normal....

Greetings

If you believe the transmission is too hot, install a transmission cooler. They only cost about $50.00 , take about an hour to install, and are necessary when towing or hauling loads. The worst enemy of a transmission is heat.

Good Luck Elroy

I'm under the impression that this is a manual transmission. If so, there is no mechanism to pump the fluid through a cooler.

You may be correct Lyn but heat isn't normally an issue with a manual transmission, unless the original poster is shifting constantly or the clutch plates are slipping.
