Hey Guys

So the inevitable has happened, my stock auto box has started to slip on up shifts while under boost after being subjected to 565whp, so am at a bit of a crossroad.

Do I do a performance build on the auto - modded valve body, updated clutches and steels and possibly up rated intermediate sprag, or do I do an R154 5 speed swap?

Bearing in mind this is a daily driver that spends time in traffic and I use for ferrying clients around, and the R154 would require a fair bit more custom work and cost at least triple what the auto route would....

Thoughts?

 

Its was bound to happen lol, just build the auto.

 

Honestly a built auto is most logical

 

Build the auto.. I beat the hell out of mine and have yet to break it....

 

Yeah, that's what I am leaning towards!

 

As much as I like a manual, a built A340E is nice. I did the penny and dimes built valve body on the A340 and had a big difference after the mod. It is able to hold up to 700 hp and its a simple mod

 

@Evlc36 for your turboed build. Did you install the turbo set up and have to do any modification to the transmission for the turbo set up to work or just an ecu ?
