If a condition of no fourth gear and/or a burned 2-4 band assembly is encountered on any THM 700-R4 transmission, the cause may be a blocked 2-4
servo exhaust hole. See Figure 1.
The use of RTV silicone sealant and/or some aftermarket oil pan gaskets may block this 2-4 servo exhaust hole causing the above conditions.
When installing the oil pan on any THM 700-R4 transmission, be certain to use original equipment oil pan gaskets so the 2-4 servo exhaust hole is not
blocked. Also, do not use RTV silicone sealant on any THM 700-R4 oil pan.
