We finally booked our SVX in for the transmission to be fixed. 3D Transmissions in Reading came and collected it yesterday.

They quoted £903 to recondition the gearbox, £274 for the torque converter and £248 for removal and refitting.
Add on the fluid and VAT and I'm expecting it to cost about £1750.
They've agreed to discount that a bit because I've given them the Level10 rebuild kit.
