input shaft Q's August 31, 2008, 05:42:27 PM i need to buy a hardened input shaft for my 88 AOD and i noticed theres some differences in styles that have me a little baffled.summit is the only place where i can find shafts at, and the list stock spline, and turbo spline. idk what that means. and secondly, one i saw there listed as non-lockup. i thought the converter is what made the difference, does that mean for whatever reason that that shaft will not work with a lockup style converter? i didnt realize the shaft made any difference.heres a link, i hope it workshttp://store.summitracing.com/egnsearch.asp?Ns=P_SRE_DisplayPrice%7C0&N=700+4294848183+4294851527+4294904006+115&Ntt=&Ntk=&rsview=sku&RC=10 Quote Selected

input shaft Q's Reply #3 – August 31, 2008, 08:11:25 PM I'm curious to know the increase in torque capacity an AOD can handle with this upgrade? Quote Selected
input shaft Q's Reply #4 – September 01, 2008, 01:35:10 AM ok, i planned on getting a lockup converter. i thought they were better for street use and that a nonlockup would make the trans run hotter and also hurt gas mileage. am i wrong? one of those links said that a lockup converter was bad? why excactly is it bad? should i go with a nonlockup? the shaft is about $100 cheaper for the nonlockup, which kind of upsets me.

input shaft Q's Reply #5 – September 01, 2008, 06:00:58 AM It's not that a lockup is bad,but you can put more power to non lockup.I had a n/l in my car even with the shift kit it shifted smoothe.Bye the way is for sale.If your staying 300hp or less thelockup would be fine.You can not mix the shafts and converters.

input shaft Q's Reply #6 – September 01, 2008, 08:41:28 AM For a mostly street use, go with the lockup... Except for some B&M converters(maybe others??) the transmission must be dissembled to install the non lockup shaft... The B&M converters are modified to use the std lockup shaft... Quote Selected

(or something like that, i read it at 2 A.M.). but i remember it was only talking about GM stuff. what does that have to do with my AOD? Quote Selected
input shaft Q's Reply #8 – September 01, 2008, 12:12:01 PM Assuming it's fairly fresh, with a shift kit and the hardened shaft it should be fine... Myself and Ronnie(chrome302jr), both sprayed our 5.0s with 125-150Hp shots and the transmissions lived... Ronnie eventually had to have his rebuilt, but he probably used 35-40 bottles of nitrous... BTW, the B&M street 2000 stall converter I sold him lived with no problem, he upgraded when the transmission was rebuilt... Quote Selected

That's being optimistic. I've searched these driveline threads for building an AOD to withstand 500 hp/500 tq, and the consensus is it'll be expensive. Maybe all that work stuffing a C6 in would be worth it afterall, lol. Speaking for myself, of course. Quote Selected

input shaft Q's Reply #12 – September 01, 2008, 01:33:39 PM Yes a aod to put up with 500 tq is asking a lot,yes exspensive,I had one made,not sure it would hold that though.I don't have that tourqe level,yet. Quote Selected
input shaft Q's Reply #13 – September 01, 2008, 11:42:48 PM yea, a t-56 or something might be an idea. i didnt htink that far ahead to be honest. i want this AOD to last at least a year. funds dont support to any trans swaps yet, i figure in a year i can save that kinda cash, and still enjoy my AOD in the meantime. i dont really wanna stick with an aod in the long run(like have one professionally built to really handle my needs) because it robs alot of power to the wheels, and i also enjoy a manual car alot more. to save the aod for as long as i can ill get that shaft and that converter as well as a shift kit and a trans cooler. and then ill cross my fingers.
