Does anyone know the ZF model for the automatic tranny used in late-model US specification Spiders? I desperately need a pan gasket and cannot seem to find one from our vendors. I'm trying to cross reference the unit with other marques in hopes of finding a source. If anyone knows the source, all this becomes a mute point and I'd be grateful to learn of it.

Thanks,
Ken

Two possibilities I can guess at. 1) try a BMW dealer, as that gearbox was used in the 3-series cars of the same vintage, so the pan gasket may be the same. 2) make your own gasket - cork and paper gasket material is available at most auto parts stores, as are sealants, which when used properly, can take the place of a gasket.

Thanks, friends. The tranny plate indicates that it's a ZF3-HP22, tough to read due to grime and position.

The pan gasket is no longer available from Alfa.

I was able to find the part as a cross referenced BMW item, BMW p/n 24.11.1.205.903.

There are numerous applications from the late 80's including BMW, Lincoln, Peugeot and Volvo. Price is about $12.

This part fits Spider's and Milano's with A/T.

Thanks,
Ken

Does anyone have a Alfa rebuild Manual for the Alfa ZF 3HP22 transmission?

What about a parts list?

Dom you really do find some useful stuff, how do you do it?? Thanks, I will find it very helpful too.

PS The speedo sender on my auto has gone again, I haven't been able to find a replacement so I am fitting an aftermarket sensor operating from a trigger wheel on the propshaft. Will post a description if it works.

Update: I have contacted JPAT to inquire about parts for the 3HP22 automatic.

I did a search for parts for this trans and there isn't a lot out there. I did a search for a used 3HP22 and found a couple. Good to have one on hand that is ready to drop in.

My car will require the front pump seal to be replaced and to check the torque converter input for being ellipsoidal. Hopefully JPAT has a replacement kick down cable.

Thank you for the link to the manual as that is very helpful.

I've got a good auto trans out of a wrecked 91 spider. It has around 85,000 miles on it. I bought the car wrecked out an insurance auction. Drove it around the block and it shifted fine.

Would like to sell it.

I don't suppose you have the rear end for sale as well? Really just looking for the ring and pinion.

I have aways wondered, that no one has try to fit a 4 speed auto in there cars,, from what I have seen the 4 speed is the same or not much bigger than the stock 3 speed auto

From one of my sources in checking for parts, the 4HP is different from the 3HP enough that it won't fit in the spider. I would imagine that the center case would be larger for the 4 speed internals. I was kicking around the idea of finding a 4HP to drop in as I would imagine that having a wider band of power in different gears would be useful, if not more economical.

I heard the same things - the ZF 4 speed is different enough in size to make it not straightforward. I have asked a few auto box specialists the same question.

From the info. I found the first three ratios are the same but fourth gives a nice overdrive ratio.

I did call a place in Birmingham (UK) which specialises in classic car conversions to a Jaguar 4 speed gearbox. They would be happy to look at the Alfa. Rough quote £7,000 or ca. €10,000 to do a conversion.....
I said thank you very much, I'll call you when I have had time to reflect :surprise:
