“'Tween:” How to Identify the ZF6HP Series Valve Body that Bridges the 1st & 2nd Generation Designs
Maura Stafford
ZF6HP19/26/32 (Gen. 1), Ford 6R60, 6R75, '09–'14 6R80 & ZF6HP21/28/34 (Gen. 2) Identification Guide
Valve components differ between Generation 1 (ZF6HP19, ZF6HP26, ZF6HP32), Ford 6R60, 6R75, '09–'14 6R80 and Generation 2 (ZF6HP21, ZF6HP28, ZF6HP34) valve bodies. Please use this identification guide to determine which generation you have to ensure correct valve kits and components are selected for your rebuild.
Gen. 1 (ZF6HP19/26/32), | Gen. 2 (ZF6HP21/28/34) |
1. Identify! | |
| 1st Generation Case Side Includes 19, 26 & 32 | 2nd Generation Case Side Includes 21, 28 & 34 |
 |  |
2. VerifyVerify OE dimensions indicated in order to select the correct Sonnax parts. | |
| Different Sized PR Valves & Sleeves* | PR Valves & Sleeves Cannot be Interchanged |
Gen. 1 (ZF6HP19/26/32) without 053 Separator Plate & Ford 6R60, 6R75, ’09–’14 6R80 | Gen. 2 (ZF6HP21/28/34) |
