Thread: Td5 auto questions

Lock up in 4th is 80kmh.
lockup in 3rd is 70kmh
unlock in 4th 70 kmh
unlock in 3rd 50 kmh

Tc stall is 3000rpm so that is why it feels different.

lockup speeds can be a little different depending on throttle position. There is a local hill near my place where lockup in 3 is less than 70 maybe even down to 60.
I have never been able to figure out exactly what the conditions for lower lock are.
no lock up in 2 or 1. When in low range if sport selected trans stays in selected gear.

regards PhilipA

Mine locks up in 3rd at 60 now. Part throttle, a little load and I mostly run in S mode
And they do lock up in 2nd.
Going up through the gears at full throttle it goes 1st, 2nd, lockup 2nd, 3rd, lockup 3rd, 4th, lockup 4th, and in the hills around here it will lockup up in 2nd once it's kicked back, too.

As said, in low range you can use manual mode, and in HDC mode it will lockup in 1st and 2nd at around the 1800-2000rpm mark once you get above HDC range.

I didn't realise yours was an auto, Rick. Ya gittin' soft in ya old age.

Oi!
Not so much of the old, please!

Only the second auto I've had, the first was an F100, 25 years ago.

The auto is damned good off road, though.

Mine locks up around 60kph in 3rd..
Then around 82ish for fourth...

The td5 auto's use the box as a sort of wind-me-up thing,, when new you wouldnt have realised/heard it. They couldve used a better turbo and a gearbox that locksup,, but then nobody wouldve bought one!!

Standard torque converter stall speed is 2800 rpm , lock up is determined by load, throttle position, temp ( must be 59 degrees or above ) drive time,and revs.
Of the dozens I have driven , including my own , I have never had lock up in 2nd !.
Unlock with trailing throttle is governed by revs ( 1500 ), so if you want to keep it in lockup from say a 90 zone to a 70 zone , don't take your foot off the throttle, just ease it back so it doesn't come out of lock up, then gently accelerate back up to speed .
Not sure what you mean by " wind and limb"

I didn't think they locked up in 2nd but I've counted the changes and watched the tach like a hawk.

There is definite lock up in low range 1st and 2nd too when in manual mode at that 2000rpm spot, and it drops out under that and reverts to hill decent.
