1991 Saab 900 automatic gearbox problem

ViestiKirjoittaja ted » Ma Tammi 23, 2017 10:32 pm

Hi

I bought a great OG900 Saab from Helsinki and have driven with it 1,5 years now. It had some leaks form the automatic gearbox and I had some repairs made to the gearbox oil pan seals, but seems that it did not help. Now the gearbox shifts up really late with the engin revving around 4000-5000 rpm-s. Has anyone here had similar probleem with Saab 3-gear automatic gearbox? Or do you know what could be the solution?

I know that in worst case scenario this probleem could mean changing the gearbox. Could you recommend a workshop in southern-Finland, who is willing to take a look on such an issue?

Have you checked your gearbox oil level lately? I once drove an OG900 which had the exact same symptom, and it simply had too little fluid in the gearbox. That would be the first thing to check before considering potentially expensive repairs. Remember to use the correct procedure (page 440-30 in this manual) or simply add half a liter and see if it makes any difference.

You can find decent repair shops in these topics:

This one in particular seems to get lots of recommendations: http://www.autohuoltoholmberg.fi/

Kiitoksia vinkeistä! I will contact the suggested repair shops.

About the oil level - I checked the gearbox oil level regularly, but after repairs in autumn I believed that all is well with the gearbox. When the shifting problems appeared it was already too late - the gearox was dry, because the seals had started to leak again. Looks like something has been damaged inside the box now. Filling it up did not help anymore.

If you are able to go to Tallin, there is also a really good Saab service called Auto tarvete. If you need to change the gear box, I'd ask for a offer from them also.
