l98 6l80e conversion help
Hi guys , i have a weird one im trying to sort a l98/6l80e conversion in to a early landrover , i have a feeling the gearbox might have a stuffed tcm, shifts gears ok on normal driving conditions, but under full throttle it hits 4800rpm and wont go any further , holds engine at the rev , gearbox wont shift up or let engine accelerate further, engine can free rev in netural no dramas etc , ive disabled all engine rev limits in that rpm, i ve tryed to command gears with scan tool but it wont hold the commanded gear ethier ? , conversion has no bcm or paddle shift wired up?
