got a bit of a problem with my mum's LTD. it occurs very rarely so its hard to pin down. basically you will be cruising or lightly accelerating and suddenly with no warning it will kick back a gear or two. scares the life out of you. it has happained on the open road and as low as about 40kmph.
I have swapped over the TPS units in the hope that they were the problem but it did it again today. because i have the same car i can swap over parts but i need some suggestions on what else it could be!
1992 DC LTD 5.0
Duel exhaust, Genie extractors, Ported E7 heads, ported lower HO inlet, 70mm maf, Underdrive Pullies
Cheak the level if it is low it will kick down (or serge) early. Also check the colour.
The filter could be blocked and you are loosing pressure.
Also as it is an 8, swap the TPS with the engine one. See how it drives.
