Hi folks.

I'm searching here and on the 'net about this but could use input.

I'm thinking of buying a '94 Jetta. From the owner:

'It has 130K km's, was a daily driver but transmission sometimes slips after engine up to temp. If I shut down engine [maybe let it cool?] transmission is ok'

I wish i could find the TSB but I did find one regarding a sensor indicating incorrect transmission fluid temps causing the transmission control module to misbehave.

Does it sound like I'm chasing the wrong cause? i.e. is it more likely that the transmission is old/abused and starting to fail?

Thanks.

Unless you're ready to shell out $2,500-$3,500 on a rebuild, I'd steer clear of a VW auto, especially if it's presenting you (or the PO) with issues.

Right ok. Ya, no way I'd spend that money. Even if I did the R&R myself. I didn't mention this, as I didn't want to risk offending any VW purists here, Smile but its quite possible I'd eventually pull the engine from that Jetta to keep as a spare for my Vanagon/Jetta swaps. If feasible, in the meantime, I'd use the Jetta to drive short distances to beer store etc.; it is still drivable up to a point.

Finding potentially lower mile ABA OBD1 engines is getting hard to do locally. But who knows how the engine has been treated. However, vehicle paint, interior looks nice.

Sorry. Forgot this detail.

Owner said that while this Jetta was owned by the PO, rodents (assumedly) damaged wires. The PO then "fixed" that with a bypass of some kind. Where, to what, I don't know. So, this is why I'm leaning towards an electrical fault at TCM or ? vs mechanical.... assuming an electrical fault in a harness could cause an issue at tranny. My wishful thinking is that the current owner is experiencing a limp mode situation vs slipping tranny though under OBD1, limp mode may not be available.

When the trans goes into limp mode, it defaults to 3rd gear. If continually driven in third gear, it will burn up the clutches in third.

An ABA is too tall for a Vanagon swap without raising the engine cover. If its a good driver, it would be an easy 5-speed swap candidate.

ha ha. Didn't know that about the Mk3 auto. Assumed they'd be better than, say, the EV auto.

TDCTDI Ok. Thanks. Assumed OBD1 wasn't capable of limp mode. Good to know about potential 3rd clutch damage. I've been running an ABA 15 engine mount angle in my '81 Vanagon. Ya, the lid tub is not optimal but I got used to it. My current ABA swap into an '88 Vanagon is at 50 and I fabricated new baskets for the mounts setting engine lower so it just about clears the engine lid.

Most any used car is a ferry ride away but hopefully I can organize a test drive. Its likely its an engine donor at best but for a few hundred CND, that could be a good deal. Most in that price range are pretty beat up.
