520Lxi Transmission slow and whining

[edbzachary@gmail.com 0]

I am trying to fix up an old 520Lxi. Great machine and have got the engine running perfectly, but it only moves slowly, and occasionally surges. I'd love any advice - from what I've read it seems like a transmission issue. I've replaced the transmission oil and filter and cleaned the power steering filter, but with no change. Any thoughts appreciated - especially if it's a quick and easy fix (parts hard to get in the UK for this old machine!). Thanks in advance,
