Hi everyone,

My car's just ticked over 300,000km's and although the engine is still strong (and is sitting on around 9.8L/100km for my daily driving), the transmission has been thumping a bit - probably for around 70,000km's or so! But I can feel it getting worse (particularly while the fluid is cold).

It's due for a tranmission service, which will cost around $100 if I get it done at my local mechanics... but I'm wondering if it's better value to get a lower km's transmission and have it swapped out. I know the transmission is going to blow sooner or later (the change between 1st and 2nd gives a metallic thump, and it's starting to get a bit more thumpish on the 2nd -> 3rd).

do the service first and then see how it goes if it doesnt improve either take it to a tranny specilist or buy a second hand gear box should be roughly $500 from a wrecker and a few hundred for labour

You could always spend a bit more and fit a manual .

Not everyone prefers manual, hell for a lot of driving it's just a pain in the arse.

On topic replacements transmissions seem to be well over a grand. Transdoctor do a replacement and upgrade for I think $1700 which seems pretty good.

does the thump come from the transmission or the diff?

If you go for a reco, it's going to be around $2k fitted. I guess it comes down to what you're willing to invest in such a vehicle.

Personally I'd look around for a low km second hand jobbie out of a wreck (with a few months warranty just in case), it's especially good that you've got VS-VY (v6 NA) to choose from. That'd drop it to about $1k fitted.

Otherwise add another $2k to the reco and you could just grab another lower km VXII.

I'm pretty sure my diff is causing a thump as well. Does the diff often thump during gear changes too? I planned to change the oil in my diff very soon (bought the oil for it the other day). It's never been changed.

Oops I should have said - I'd be looking for a 2nd hand low km's jobbie, there are a crapload of them on Ebay.

I saw one listing with a <150,000km's trasnmission for about $150, and they charge $350 labour to fit it (including new oil and new filter etc). So about $500 all up with 6 months warranty.

I'm hoping to find the most decent low km's one I can find, and pay my mechanic labour to fit it... but I really don't know how much time it would take to swap over a transmission.

I'd be a bit suss about one for $150 with a claimed <150k. Sure it wasnt an auction reserve? Usual going rate is $4-500. Tack on a few hours labour and a service and it's another $400 (ish).

Change the fluid!! It's cheap and you'll be amazed at what it can do!! For both trans and diff!!

You might get another 100,000km out of them both! But you also might not......
