Im new to this forum but have found it very helpful, Ive had my ls 400 91 for 5 months and recently the diff went so replaced the diff, replaced the diff fitted it all properley and turned the car over only to find it had no drive no 2nd or L and only has drive in reverse all the selectors are working and there is plenty of fluid checked while running , when the diff went it still had drive as the propshaft still rotated.
any help would be great guys
thanks
