ansonivan Posted June 16, 2010 Report Share Posted June 16, 2010 My 97 e150 has a delayed 2-3 shift, alldata lists an updated 2-3 accumulator piston as the fix. My plan: - replace 2-3 accumulator piston with updated part # F7AZ-7H292-AB - perform "j-mod" aka selectively drill the valve body for firmer shifts with less slippage - replace filter Any feedback on the viability of the J-mod and my delayed shift repair approach is appreciated. Does anyone have a specific Ford dealer/parts guy from which the prefer to purchase parts? Quote Link to comment Share on other sites More sharing options...

ansonivan Posted June 16, 2010 Author Report Share Posted June 16, 2010 Checked them out, they don't seem to be using ford part numbers so I'm having trouble finding the correct parts. Quote Link to comment Share on other sites More sharing options...
ansonivan Posted June 16, 2010 Author Report Share Posted June 16, 2010 They also don't list a 2-3 accumulator piston for the 4R70W Quote Link to comment Share on other sites More sharing options...
Patterson Posted June 16, 2010 Report Share Posted June 16, 2010 This one? http://www.bulkpart.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=2&Product_Code=A76932EA&Category_Code=AODEservo&Product_Count=8 Quote Link to comment Share on other sites More sharing options...
ansonivan Posted June 16, 2010 Author Report Share Posted June 16, 2010 Could be the correct part but it does not specify 4r70w, only aode. Also, wtf weird part numbers? Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted June 16, 2010 Report Share Posted June 16, 2010 for about the same money and a small rewire you could use a 2000+ trans instead and not need to mod anything try a t-bird forum to get all the correct info Quote Link to comment Share on other sites More sharing options...
ansonivan Posted June 17, 2010 Author Report Share Posted June 17, 2010 Found oem ford 1-2 and 2-3 acc pistons on ebay for $21 shipped. If (when?) this transmission goes bang I'll look into swapping in a later unit. I should be able to do all the work I listed in a few hours for under $100 including a switch to full synthetic Mobile1. Cheap maintenance > slightly more expensive and time consuming replacement.
