Need To Rebuild 4sp Ba Auto

[ford_allen]

so guys what price range shoul I look for and the nizpro gear boxes for 2300, is that for bringing the box to standard or fixing it and also replacing some parts with better the parts?

what I wanna know is if they only fix the wrecked parts or there is a prepared list of works they do in a price of 2300?

so it sounds like there is no way for me to get my box rebuild for 1500-1750 by some decent place?

Nizpro rebuild the whole box including new parts. also that price includes taking the box out and putting it back in.

You could try bayswater autos for a better price.

so, does it mean nizpro rebuild the transmission with all new and better parts also they replace all the main parts in the box, so box become fine again and all the problems on the box are gone?????or they only fix and replace the parts gone?nt all?

is that how it is? sorry guys if I ask so much details, just I wanna know how it is before paying too much money on it? and also how much would it be to put better histall converter on it while getting it rebuilt?

Maybe just ring them and ask, as im not 100%

[ford_allen]

and does anyone know how much kewish and bayswater rebuilds with histall and without?

[ford_allen]

fanx for your help tpurv4....and explainations

[ford_allen]

so anyone has any idea about rebuilding? is it just like fixing the problem and wrecked parts or replacing the main parts of the transmission with brandnew and better parts?

hi guys, I did some research on what can be done to 4 sp auto and I made a list...how do u think about these things guys? and which are should be worth to get it done?

1) heat treated shafts and gear sets

2) upgraded input shaft

3) kevlar band(if you get better and stronger drum, otherwise it will break standar drum)

4) valve body work(Chris from bluepower said it would blow the transmission out)

5) higher pressure selonoid (while getting it rebuilt, just replace them and This applies more clamping pressure on the band to get additional grip for the increased torque)

6) new stronger clutches (serrated bf spec clutch pack for the gears(internal clutches related to 3rd and 4th gear are plain surface finish, but they can be replaced with serated surface like 1st and 2nd gear)

7) some mods to the drum (larger oil bleed holes? to aid in dispelling oil quicker under the band to aid in quick changes.

Drill out ports and countersunk

9) Drill out C3 Drum

10) Mod for delay in reverse

11) Fit C3 drum saver

12) Replace pistons if needed (C1---C2---C4)

13) internal seals and other internal similar things to be replaced

14) titanium planetary gears are good as I heard and also au planetary is better than ba

15) Au transmission pump(au pump is thicker than ba one, it protects from exploidig)

16) Insatll Hi Energy clutches kevlar bands and rose bestos steals

17) hi stall converter ( common hi stalls used on these cars are TCE and Dominator with a lock up clutch plate, there must be many brands)

and also decent flush and cleaning all the dirt from your transmission of course

and by the way how about preston? service and job quality and price? it is close to my house that's the why

The most important thing in getting these boxes to survive is get it to shift hard, thereby decreasing slip between shifts and decreasing wear.

You can decrease shifts a number of ways, but the most effective way I have found is by eliminating the function of the S3 S4 and S5 solenoid. These solenoids are there to give the box a nice soft shift.

If you try and firm the shift via the S5 you wont get the best shift under hard load.

Dont forget that one of the bands break on this box also. You can reinforce the weak band and there is a guy in the East that can reline your modified bands in a performance lining and its quite cheap. Kevlar has its good points and bad points.

Keep up your good research and try and work out the must do's from the things that really wont do much.

I think there is also much to be gained by using different transmission oils which firm up the shift.
