I’m thinking about doing the bam transmission upgrade in my 39 I’ve already converted to NXT to number sixes. Is there anyone out there that has done the upgrade in a 39 top gun.

Can't answer from direct experience but Considering you eliminated a hp capacity of the NXT and addressing the limited capacity of the stock trans, keep in mind when buying replacement trans - the Stage 4 kit will turn a stock 700 into 900+ with a bolt on+ reflash.

Sooner or later most engines get a kit of some stage to up the performance
