Hp4-14 (4Hp14) Automatic Gearbox

[Mad Professor 7]

Good day all.

 

I am on a quest to try and find out as much details as I can regarding the HP4-14 (4HP14) automatic gearbox.

 

Well all I am really trying to find out is what is the max safe bhp/torque thease gearboxes can cope with.

 

Looking on Wiki I found this box is fitted to the following.

The ZF 4HP14 is a four-speed automatic transmission for passenger cars from ZF Friedrichshafen AG. Introduced in 1987, and produced through 2001, it was used in Citroën, Peugeot, and Daewoo front-wheel drive cars.

Does anyone happen to know if it would cope with being used on a 205 1.8 STDT?

 

Thanks for your time.

Is the gearing right for a diesel?

[Anthony 1,003]

Otherwise, what slushbox was fitted to the later XUD9 turbo engines like the Xantia for example? That logically should be well suited.

I did a lot of study into this when I had my Gentry auto box issues, this 4hp14 is at it's limit with anything much over 120bhp/120lb/ft.

 

You would be much better off with the next one up which is used for the turbo diesels in the PSA group of that vintage, I think it is called the 4hp18.

 

The bigger one is the 4hp20 which is used for the big PSA cars with loads of power and torque.

Not another project.....

I fitted an Xantia turbo engine onto this 'box on my trackcar, and waited for it to break before fitting a XM turbo autobox. Still waiting... I have fitted an oil cooler though, which i believe has helped it to last as well as it has.

I found an XM turbo autobox in the garage the other day, if anyone wants it PM me before I weigh it in...

Jackherer: Is that the 4HP18 gearbox? and if so is it complete?

Yes and yes. I pulled it out of my XM along with the engine because someone on here thought they needed it and I think I took everything out, it has the gearstick etc still with it.
