ommot7 Posted October 11, 2021 Report Share Posted October 11, 2021 Hello, iv just picked up a 14litre Lupo that has a 1.0litre gearbox in it. It runs fine despite the gear timings however if the gearbox is maxed out, say sat at 80mph for 30mins or so it flicks up the check engine light and the car judders when pulling away. Is this something to be concerned about or fairly normal for a 1.0 box in a 1.4? thanks Quote Link to comment Share on other sites More sharing options...
Skezza Posted October 17, 2021 Report Share Posted October 17, 2021 Odd combination. Most people who have done such a swap go for a 1.4 gearbox in a 1.0. Quote Link to comment Share on other sites More sharing options...
ObjectiveAway Posted October 18, 2021 Report Share Posted October 18, 2021 Firstly, this set up is, most probably, made just for cheap repairing and selling Lupo with broken 1.4 gearbox. Secondly, Lupo petrol engines (except FSI) don't know gearbox speed and Lupo manual gearboxes do not have any connection to ECU, therefore check engine source is just from engine. Connect OBD2 and read the check engine reason, engine should work fine no matter how long you were driving in high revs. Quote Link to comment Share on other sites More sharing options...
