A3 or stay A4?

[LT1CST]

Well here we are again. This is my third 4l60E tranny that I have owned in my LT1 Camaro. My car is currently a stroker and is assigned to the drag strip only and im not sure if I want to go with the Th350 or 400 or rebuild AGAIN the 4l60e. I would like to hear from both people with both transmission to give insight pros cons etc... Thanks

question: does the "e" in the tranny code refer to electric overdrive? in which case the a4 has one but the a3 does not?

[LT1CST]

Yes. 4l60e is the electronic shifting tranmission. 700r4 is the same as the 4L60E but with out the "e". And its an 4speed Auto. I have no use of the OD auto anymore. MY car is strickly a drag car. Thats why im considering going old skool with the TURBOS

If you're blowing 4L60Es, then dont bother with a TH350. It is going to have the same size internals. If it's a drag only car, there's really no debate... a TH400 would be perfect for you.

who did your rebuilds?

[LT1CST]

A local tranny shop did. Turbo 400 is what I was leaning more towards. What trannies are you guys running?

I couldn't break the TH400 in my 67 with a built 427 rat motor so I think it'll handle a small block.

On a side note: Have you considered a built Powerglide?

TH400 = Practically Indestructible.

TH350 is a stout transmission too, they definitely seem to be stronger than 700R4s or 4L60s.

a t400 is slightly heavier and will use a little more horsepower than a t350, but is the same length of a 7004r so you dont need a new driveshaft or have to move the crossmember. it also has a higher first gear than the t350. how much horsepower and torque is your engine putting out?
