Welcome to the club, Slim. The 700R4 has been around long enough that the weak points have been found and corrected by the aftermarket companies. You can make them almost bullet proof. I would look at shops like FinishLineTransmissions for a remanufactured unit. I'm sure it will be alot easier than changing to a 5speed.
Standard transmission for 89 1/2 ton 4x4 Sbn
My 1989 4x4 5.7 TBI currently sports the ubiquitous 700R4 tmission. It has never given me any real problem, but I'd like to travel in my vehicle, and I just don't really trust the 700R4 at 180,000 miles. I'd like to convert to a standard transmission, and am looking to find a suitable standard transmission.
Compound low is really not necessary in my application, since the xfer case would provide crawl speed low if necessary. Can anyone say what should be readily available that will somewhat fit? Has anyone else done same?
I've seen new 5 speeds with 1:1 top gear, and new 6 speeds with overdriven top gear, very pricey.
Thanks in advance for any insight.
