Mike, Malcolm and all,

I did as you suggested and changed the ATF and fitted a new filter, last changed 5 years ago and 25k miles so it needed doing, oh and put in a bottle of Trans-X as people seem to rate it.

Next I checked the Bowden cable, I had checked all the cables awhile back, it felt loose i.e. no tension on it so I left it alone but when I popped off the connector it was obvious there was tension on it, I adjusted it so there was no tension and refitted and went for a drive… problem fixed, now drops into top smoothly.

Thanks guys.

I know the original buyers were never expected to service these cars but filling that transmission lying underneath is a pain.



My auto transmission won’t change into 4th/top gear unless I come of the throttle and then changes with a thud, all other changes up and down are fine, I think it’s the original transmission in which case it’s got 288k on it, I’ve checked the ATF level and checked the vacuum line and the modulator, both hold vacuum, I think the cables on the manifold are adjusted right. I’m ok on the rest but autos are a mystery to me.

Could it be something fixable without tearing into it or should I just look for another trannie, it’s got to come out as I’m replacing the TT soon.

Any ideas appreciated.

You could try loosening the Bowden cable a turn or two...

Unfortunately, I had the same issue with an 89'S4... I had to shift into neutral and back to drive to get it to upshift... Transmission started slipping badly soon after...

If you can swing the funds, install a superclamp when you have your torque tube out. Are you going with Superbearings?

Hi Mike,
I will check the Bowden cable, Re the superclamp and superbearings, not sure which way I'm going yet, if I need another transmission funds will be tight but I know what I should do....

How old is the tranny oil and filter?

I'd change both and have the level set perfectly before jumping to further conclusions.

You said fluid level was correct, but If you havn't changed oil and filter, or it's been more than a year or 10-15K miles, it's a really good idea.

The update, hopefully should be below.

Make that at the top.
