CAUTIONS: Adapter plate kit F-15741-TL29PL is required
to help secure No. 2 rear control valve body to VB-FIX
(Figures 1 & 2). If you do NOT have these particular
designated holes on your adapter plate you have an
early-style and it must be modied for this application. For direc-
tions on how to modify your early-style adapter plate, go to
www.sonnax.com and search F-15741-TL29PL.
1. Disassembly
a. Remove OE retaining clip and save for reuse.
b. Remove and discard OE boost sleeve, boost valve,
spring and clutch control valve.
2. Bore Reaming

b. Install Sonnax boost valve, boost sleeve and spring.
