well disappointed, guess i dorked something up! but staying positive
Its a new build, pretty much everything was done to the trans, I spent ALOT of time paying attention to detail and everything else so something like this wouldnt happen. Lots of money too.
When out for a road test, I put her in overdrive, and accelerated very slowly, it shifts at about the right time, but it feels like it down shifts - and hard too. probably going about 25 mph, then it "shifts" and the tires actually skid slightly and slow way down, almost slows to a complete stop before kicking back into regular first gear. Its almost like the converter is locking or reverse is trying to apply. I noticed theres a nice pressure drop as it shifts and then it comes back up. it does it in all forward gear positions and all throttle positions (havnt tried WOT -afraid of breaking something) it does hold low however and first feels fine. unplugging the tcc plug has no effect.
Here are the pressures
engine - 406 sbc
engine temp 200*
trans temp 170*
min t.v. (hooked to carb adjusted per bowtie instructions)
idle - 800ish in nuetral
- 650ish in gear
P 112
N 135
R 112
4 112
3 112
2 150
1 185
max t.v
idle - alittle bit faster
P 230
N 125
R 225
4 165
3 155
2 160 (tv has no effect on pressure in any position for 2 and 1)
1 165 (even faster idle - 205 )
min tv pressure look good?
but max tv i have a problem in all gears neutral and reverse look ok?
what is going on here??

-
mods
- bowtie overdrives TV made ez kit for holley carb
- adjusted to their instructions (2-4 lb increase from no tv idle pressure)
- their TV valve spring (very stiff)
- carb cam all the way forward (all the way back just causes the problem shift sooner)
-billet 9x11 converter 3200 stall
-ck complete pump installed untouched
-ck billet input shaft with solid rings
-ck billet OD carrier
-3 friction OD pack
-ck billet od ring gear
-ck billet forward drums
-sent the entire front and middle sections to chris for him to check and fix
- hardened sunshell ofcourse
- stock type and count clutches everyelse other then reds and kolene in the directs
-all new bushings, bearings, washers, seals, o-rings, sprags, rings etc etc.
-alto red wide band
-all clearances where they needed to be
- updated 3-4 accum piston with updated spring
-16 spring direct retainer assembly
- dual fed - (center ring removed, inner direct seal removed and support bolt plugged)
-ck revised separator plate
-ck billet servo (servo cushion spring retained)
- blocked 1-2 accum
-ck billet band anchor
-servo return spring from transgo (white)
-2 new wave springs in lo/reverse
-rollerized lo/rev housing
-no holes drilled anywhere other than a enlarged lube hole on front carrier
-art carr deep pan
-stock governor (figured i would just manual shift it at 6000)
-bowtie overdrives lockup kit with manual switch for 3rd/2nd gear lockups
-transgo springs in valve body (blue 2-3 spring, white accum valve spring, beige line bias spring, green M.T.V. downshift spring, and the 3 small "tough", blue and red springs on the front of the smaller tv valve)
-bowties TV spring (stiff!)
-ck 3rd gear correction spring
i think thats pretty much everything.
if it was in ck's book i most likely did it
please help me out!![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
