Replace torque converter or rebuild trans?

(Previous experience with a Territory, is the extra oil, keeps down trans oil temps, therefore aids in lifespan when frequently towing.)

But one point, that seems to be overlooked here is this, has anyone added a 2nd Transcooler, or a larger aftermarket one, as keeping the oil cooler even by uptown 10deg cel, can increase lifespan. As its quite common for some to fit a watchdog, or similar to monitor the oil temps.. Just curious..

As, im at the point where the convertor is getting replaced, and on the fence about a rebuild trans, so whilst im there it makes smart sense to help the oil stay cooler, or at least fit a gauge..

Any suggestions?

I believe ShaneGTR has a 2nd cooler, easy to add as the fittings are just normal hose barbs,unless you know for sure that the clutches and stator bushes are badly worn i think rebuilding the valve body as Eric did should sort you out.

No extra cooler for me - just an inline filter

I knew it was one or the other [thumbsupbig].

I had planned to get the torque converter and re-build at the same. Mechanic at MR Automotive talked me out of the rebuild. As I am now towing a 3t boat I got the heavy duty cooler. Hard to say how effective it is as I hadn’t towed the boat with the original cooler, so can’t compare.

Definitely do a couple of tubes of Dr tranny, my TC was shuddering terribly around the 1800 RPM with revs fluctuating as it tried to lock up.
I did a triple flush, new seals etc and it was but still shuddering then added three tubes of Dr tranny. Over 18 months now and I am still driving it with no shudder, get a bit of slippage on 3rd but I drive it sedately to prolong its life. It would not be up to beach work that is for sure.

At some point in the near future I expect I will need a new TC and will get the transmissions full overhauled including the mechatronics and solenoids.

I'm hoping to get another 12 months out of it.

Do the triple flush and seals then add Dr tranny. Its a pretty easy job, I did it myself one Saturday morning.

Hope this assists with your decision making and cashflow!

cheers

Would love to know the outcome of this issues...just purchased a 2009 Range Rover sport which has quickly developed a shudder and trans fluid leak😫( also in Perth WA)

You can start with some Dr TRanny to see how that goes. See if can find where the leak is and fix that then refill to the right oil level. Your tranny might even be low on oil if there's a leak and that might be the issue.

Other option is a transmission service, metal pan and filter and go from there (assuming it doesn't have a metal pan already). They can add Dr tranny as well.

Yes these don’t leak except for a couple of very cheap seals. The 4 seals above the mechatronics unit need changing also and affect smoothness.

You may not have the correct level or the correct fluid. Is the fluid black and burnt smelling or clear and nice?

Is there any evidence of earlier oil changes? At this age without servicing its highly likely the gearbox is not well.
