|
|
I have a R reg 1997 Colordo GX Manual the problem i am having is. Driving on the motorway in 5th gear then coming to the end of the motorway to a roundabout and just about to change down to 4th and it feels very stiff to get from 5th. also reverse is the same, it is a little stiff to get into these gears but even harder to get out of them even with the engine switched off. any ideas what the problem would be? all the other gears are OK.
Thanks |

first thing I would suggest is changing the oil, and use the correct specification. (Especially if it is a GL4 spec)
I am not sure about the colorado but I understand that older GL4 spec gearboxes can be damaged if later GL5 spec oils ae inadvertantly used in them! |

Could this be the problem if the oil levels are low.?? Will have to have a look when it stops raining. |

Don't just top it up - change it!
It's an easy job. Use the right oil and check the levels, go for a drive and check again.
Any haynes manual will show you how - easy job. Axle stands make it even easier.

Just spoken to Toyota and they haven't come across this problem before, Colorado going in to Toyota to have the oil in the transfer box and gearbox changed, hope this will cure the problem cost £45.00 inc vat @20%.
I don't know if this price is OK.
Thanks for the reply. Will let you know if it works.

Had the oil in the gearbox changed today, Toyota said the transfer box oil didn't need changing, driven it back home seems a very slight improvement but not what I expected, still very stiff only did 8 miles, hope it will improve when i take it for a run. Gearbox Oil 75W90 1 litre x 4
Thanks for the replies

I would start by asking the dealer what the oil was like that came out - were there any deposits in it?
When you have gearbox/diff/transfer case issues, you can learn a lot from the oil that comes out.
Unfortunately it sounds like an issue with the box which will require it to be stripped and checked. _________________ Cheers,

You need to check whether you have a g/box or clutch problem.
Drive far enough and hard enough to promote the problem.
Then, with the engine running, attempt to change gear. Note the stiffness.
Then, switch the engine off and re-test. Is the gear change easier? If you notice no difference, the clutch is disengaging correctly. If you note a slight improvement, you have a degree of drag due to a build up of dirt on the g/box nose, this is the extension on which the clutch release bearing slides, or the clutch mechanism is not travelling far enough to correctly release the clutch. If you note a considerable improvement to the point that you are happy with the gear change then you need to check out the clutch/release mechanism.
With my own KZJ 70, the g/change improved when the oil was operating at a higher temp. than normal driving achieved ie. heavy going "off-road". I found that changing to a fully synthetic oil had the same effect. Based on the cost of the oil change you are running a standard mineral oil. as a matter of course I would change it for a fully synthetic.

I have never had a problem with the clutch, it works fine, When i put it in reverse (with or without the engine running) it feels very stiff as if something is holding on to it, it feels as if you are trying to sqeeze something which is slightly to large into a smaller hole the same on 5th gear, it goes in easier when going up rather than changing down from 5th to 4th.
I have just been out to move the Colorado and it still very stiff gettting it into either 5th or reserve. The change of gearbox oil hasn't done anything.
The mechanic who changed the oil told me that the box would have to come out and that it was an easy job to take out but where do you start to look, and how much labour costs!!
